1. 1. Solve the equation |x + 2| = 62. Solve the equation |3x - 2| = 2x + 43. Solve |2x - 1| = |x + 4|tolong, Kak. ini harus sekarang
Jawaban:
1. |x+2|=6
x+2=6
x= 6-2
x= 4
x+2=-6
x= -6-2
x= -8
maka hp nya adalah x= -8; x= 4
2. |3x-2|= 2x+4
3x-2= 2x+4
3x-2x= 4+2
x= 6
3x-2= -2x-4
3x+2x= -4+2
5x= -2
x= -2/5
maka hp nya adalah x= -2/5; x=6
3. |2x-1|= |x+4|
2x-1= x+4
2x-x= 4+1
x=5
2x-1= -x-4
2x+x= -4+1
3x= -3
x= -3/3
x= -1
maka hp nya adalah x= -1; x=5
2. Q5. Solve the equation -4(10 + 3x) - (x + 8) = -9
Jawab:
x = -3
Penjelasan dengan langkah-langkah:
-4(10 + 3x) - (x + 8) = -9
[-4.10 + (-4)(3x)] - [x + 8] = -9
[-40 - 12x] - x - 8 = -9
-40 - 8 - 12x - x = -9
-48 - 13x = -9
-48 + 9 = 13x
-39 = 13x
x = -39/13
x = -3

3. 9 Given the functions f(x)= x² - x and g(x)= x² – 3x – 12,asolve the equation f(x) = 6b solve the equation f(x) = g(x).
Penjelasan dengan langkah-langkah:
a.) f(x)=6
=>6=x²-x
x² - x - 6 = 0
(x + 2) (x - 3) = 0
x = -2, and x = 3
b.) f(x) = g(x)
g(x) = 6
=>6=x²-3x-12
=> x² - 3x - 12 - 6
=> x² -3x - 18
(x - 6) (x + 3) = 0
=> x=6,andx=-3

6. 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]

19. 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]
