3. Directions: Solve the following quadratic equations by: Extracting square roots 1. x² = 16 2. t² = 81 3. x² - 16 = 0 Factoring 1. x² + 7x = 0 2. 6s² + 18s = 0 3. x² + 3x - 10 = 0 Pls help I really need this now.
Extracting square roots
1. x² = 16
x = ±√16
x = ±4
x = -4 or x = 4
2. t² = 81
t = ±√81
t = ±9
t = -3 or t = 3
3. x² - 16 = 0
x² = 16
x = ±√16
x = ±4
x = -4 or x = 4
Factoring
1. x² + 7x = 0
x(x + 7) = 0
x = 0 or x + 7 = 0
x = 0. x = -7
2. 6s² + 18s = 0
6s(s + 3) = 0
6s = 0 or s + 3 = 0
s = 0. s = -3
3. x² + 3x - 10 = 0
(x + 5)(x - 2) = 0
x + 5 = 0 or x - 2 = 0
x = -5. x = 2
4. Directions: Solve the following quadratic equations by extracting square roots. 1. x² - 144 = 02. 2s² = 503. x² - 16 = 0Pls help.

5. Directions: Find the solutions of each of the following quadratic equations by completing the square.1. x² - 2x = 32. s² + 4s - 21 = 03. r² - 10r = -17Pls help.
Jawaban:
1. x={-1, 3}
2. s={-3, 7}
3. r={5 - 2√2, 5 + 2√2}
Penjelasan dengan langkah-langkah:
1. x² - 2x=3
x² - 2x + 1=3 + 1
(x - 1)²=4
x - 1=√4
x - 1=±2
x1:
x - 1=2
x=3
x2:
x - 1=-2
x=-1
2. s² + 4s - 21=0
s² + 4s=21
s² + 4s + 4=21+4
(s + 2)²=25
s + 2=√25
s + 2=±5
s1:
s + 2=5
s=3
s2:
s + 2=-5
s=-7
3. r² - 10r=-17
r² - 10r + 25=-17 + 25
(r - 5)²=8
r - 5=√8
r - 5=±2√2
r1:
r - 5=2√2
r=5 + 2√2
r2:
r - 5=-2√2
r=5 - 2√2
hope that helps :D

9. How do you solve -4k^2 − 8k - 3 = −3 - 5k^2 by factoring?
Jawab:
k1 = 8, k2 = 0
Penjelasan dengan langkah-langkah:
-4k² - 8k - 3 = -3 - 5k²
-4k² + 5k² - 8k - 3 + 3 = 0
k² - 8k = 0
k(k-8) = 0
k = 0; k = 8
10. Write the quadratic equation given its solution x = 3, x = 4
x=3 and x=4
We get
x-3 = 0 and x -4 = 0
Next to do
(x-3)(x-4) = 0
x²-7x+12 = 0
Hope this will help
11. Arrange the quadratic equations whose roots are: a. 2 and 10 b. -9 and -4 c. 1/2 and 6 d. -3 and 7
a. (x - 2)(x - 10) = 0
x² - 12x + 20 = 0
b. (x + 9)(x + 4) = 0
x² + 13x + 36 = 0
c. (x - 1/2)(x - 6) = 0
x² - 6x + 3 = 0
d. (x + 3)(x - 7) = 0
x² - 4x - 21 = 0
So the quadratic equations whose roots are 2 and 10, -9 and -4, 1/2 and 6, -3 and 7 are x² - 12x + 20 = 0, x² + 13x + 36 = 0, x² - 6x + 3 = 0, x² - 4x - 21 = 0 respectively
NB : Perlu diingat bahwa untuk mendapatkan persamaan kuadrat dari akar-akar yang diberikan, kita harus mengalikan akar-akar yang diberikan dan menambahkan atau mengurangi konstanta yang diperlukan agar sama dengan 0.

14. Solving systems by elimination
-3x - 3y = 12
-4x + 3y = -24
---------------------- +
-7x = -12
x = -12/(-7)
x = 12/7
-3x - 3y = 12 (× 4)
-4x + 3y = -24 (× 3)
-12x - 12y = 48
-12x + 9y = -72
---------------------- -
-21y = 120
y = 120/(-21)
y = -40/7
so HP = {12/7 , -40/7}

coba tulis soalnya dgn baik ,agar klw mau di jawab bisa
18. a + b = 25 a + d = 10 b + d = 35 What is the quadratic equations which the radixes are 2a and 3b
a + b = 25
a + d = 20
b + d = 35
a + d = 20
a = 20 - d
b + d = 35
b = 35 - d
a + b = 25
(20 - d) + (35 - d) = 25
20 - d + 35 - d = 25
55 - 2d = 25
-2d = 25 - 55
-2d = -30
d = 15
a + d = 20
a = 20 - d
a = 20 - 15
a = 5
b + d = 35
b = 35 - d
b = 35 - 15
b = 20
2a = 2(5)
= 10
3b = 3(20)
= 60
x₁ = 10
x₂ = 60
(x - x₁) (x - x₂) = 0
(x - 10) (x - 60) = 0
x² - 60x - 10x + 600 = 0
x² - 70x + 600 = 0
Determine all the variables
Eliminate a from Equation 1 and 2
a + b = 25
a + d = 20 -
b - d = 5
Store the new equation to eliminate the d in Equation 3
b - d = 5
b + d = 35 +
2b = 40
b = 20
Substitute back b to determine the value of d
20 - d = 5
d = 20 - 5
d = 15
And, substitute back d to determine a
a + d = 20
a + 15 = 20
a = 20 - 15
a = 5
From these known variables, the radixes of the quadratic equations are:
x₁ = 2a = 2(5) = 10
x₂ = 3b = 3(20) = 60
Arrange the quadratic equations:
[tex]$\begin{align}(x-x_1)(x-x_2)&=0 \\ (x-10)(x-60)&=0 \\ x^2-10x-60x+600&=0 \\ x^2-70x+600&=0\end{align}[/tex]
19. apa yang di maksud dengan factoring
Anjak piutang (bahasa Inggris: factoring) adalah suatu transaksi keuangan sewaktu suatu perusahaan menjual piutangnya(misalnya tagihan) dengan memberikan suatu diskon. Ada tiga perbedaan antara anjak piutang dan pinjaman bank.

Jawaban:
Dengan demikian dapat disimpulkan bahwa pada prinsipnya anjak piutang syariah akan memberikan manfaat pembayaran piutang lebih cepat dari jatuh tempo, menambah dana segar perusahaan, dapat membantu peningkatan keuntungan, merupakan sarana peralihan risiko tagihan yang tidak bisa dicairkan, serta akan memberikan.
