2. solve the quadratic equation below
Step by step explanation
_________
Nomor 1
_________
[tex]\begin{aligned}\rm \frac{5x+12}{3x}&=\rm x\\\rm 5x+12&=\rm 3x^2\\0&=\rm 3x^2-5x-12\\0&=\rm (3x+4)(x-3)\\&\bf x=-\frac{4}{3}~atau~x=3\end{aligned}[/tex]
_________
Nomor 2
_________
[tex]\begin{aligned}\rm \frac{20-8k}{k-5}&=\rm 3k\\\rm 20-8k&=\rm 3k^2-15k\\0&=\rm 3k^2-15k+8k-20\\0&=\rm 3k^2-7k-20\\0&=\rm (3k+5)(k-4)\\&\bf k=-\frac{5}{3}~atau~k=4\end{aligned}[/tex]
3. solve the equation below x^2 = 3x + 2 = 0
Assume that the typo in the right side of x² is a pus (+) symbol.
So,
x² + 3x + 2 = 0
Factorize it.
(x+1)(x+2) = 0
Get some radixes:
x₁ + 1 = 0
x₁ = -1
x₂ + 2 = 0
x₂ = -2
So, the solution of the equations are:
x = {-2,-1}
[tex]\displaystyle x^2+3x+2=0\\x^2+2x+x+2=0\\x(x+2)+1(x+2)=0\\(x+1)(x+2)=0\\\\x+1=0\\x=-1\\\\\text{or}\\\\x+2=0\\x=-2\\\\\boxed{\boxed{S=\{-1,-2\}}}[/tex]
4. change the sentences below into passive voice!a. The teacher helps the student
The student is helped by the teacher
5. 1) What is the y-intercept of the quadratic equation below? * y = x2 - 6x + 9
Penjelasan dengan langkah-langkah:
titik potong persamaan kuadrat
y = x² - 6x + 9
- titik potong terhadap sumbu y, x = 0
y = 0² + 6(0) + 9
y = 9
titik potongnya (0, 9)
- titik potong terhadap sumbu x, y = 0
x² - 6x + 9 = 0
(x - 3)(x - 3) = 0
x = 3
titik potongnya (3, 0)
6. to find new quadratic equation if given an equation with the roots p and q and the roots are 2p+1 and 2q+1 (how to solved) pake bahasa indonesia nggak apa
kalo misal kasih cara tapi nanti pake cara panjang gak apa apa kan
aduhh.. maksudnya apaan sih gak ngerti....
7. the following is meant by (disolved oxygen) is
Penjelasan:
Dissolved oxygen refers to the level of free, non-compound oxygen present in water or other liquids. It is an important parameter in assessing water quality because of its influence on the organisms living within a body of water. In limnology (the study of lakes), dissolved oxygen is an essential factor second only to water itself ¹. A dissolved oxygen level that is too high or too low can harm aquatic life and affect water quality.
8. Match the best responses in the box below with the following expressions1. Student A : I wont the writing contestStudent B : .......
Jawaban:
Student B : why don't you want to join the competition?
Penjelasan:
maaf kalo salah
9. solve the equation below 3 - 2x - x^2 = 0
Use some tricks.
[tex]$\begin{align}3-2x-x^2&=0 \\ \text{Multipty both }& \text{sides by (-1)} \\ (-1)(3-2x-x^2)&=(-1)(0) \\ -3+2x+x^2&=0 \\ x^2+2x-3&=0 \\ (x+3)(x-1)&=0\end{align}[/tex]
The correct x are:
x = {-3,1}
[tex]x^2-x+3x-3=0 \\ \\ x(\frac{x^2}{x}-{x}{x}+3(\frac{3x}{3}-\frac{3}{3})=0 \\ \\ x(x^{2-1}-1)+3(x-1)=0 \\ \\ (x-1)(x+3)=0 \\ \\ \\ x-1=0 \\ \\ x+3=0 \\ \\ x=1 \ dan \ x=3 \\ \\[/tex]
Jadi x∈{1,-3}
10. create an equation from the word below•best•big• cool•amazing
1) my best friend is beni
2) the house is very big
3) the guy is so cool
4) You do flips that's amazing
11. solve the equation below[tex]5 {y}^{2} + 2y - 3 =0 [tex]
Penjelasan dengan langkah-langkah:
5y^2+2y-3=0
5y^2+2y=3
y^2+2/5y=3/5
y^2+2/5y+(2/10)^2=3/5+(2/10)^2
(y+2/10)^2=16/25
(y+1/5)^2=16/25
Penyelesaiannya=y1=-1,y2=3/5
Bentukalternatifnya=y1=-1,y2=0,6
Semogaberhasil!!!!!!

rumus : subject + modal + verb 1 + object/complement
