Question

Can anyone help me with this?

Answer 1

a. x=4 or x=−10

b. x= 3/2 or x= −8

Explanation:

(FOR LETTER A)

Step 1: Factor left side of equation.

(x−4)(x+10)=0

Step 2: Set factors equal to 0.

x−4=0 or x+10=0

x=4 or x=−10

(FOR LETTER B)

Step 1: Factor left side of equation.

(2x−3)(x+8)=0

Step 2: Set factors equal to 0.

2x−3=0 or x+8=0

x= 3/2

or x= −8
