(3x-1)=0 solve 3x+2=0

+ 1 +1 -2 -2

_______ _______

3x = 1 3x = -2

x =1/3 x= -2/3

check for to make sure both solutions work by plugging back into the equation

Answer:

x = -2/3, 1/3

Explanation:

Step 1: Factor

(3x + 2)(3x - 1) = 0

Step 2: Find roots

3x + 2 = 0

3x = -2

x = -2/3

3x - 1 = 0

3x = 1

x = 1/3
