Use the zero product property to solve them. (x+8)(2x-7)=0 (3x-5)(4x+1)=0 (x-12)(x-4)=0 (5x+2)(x+21)=0

Question

Each equation is in factorized form. Use zero product property to solve.

Answer 1

I will solve one of them for you, and then you try the others.  They are all solved the same way.

 

(x + 8)(2x - 7) = 0

 

Then

 

x + 8 = 0 ⇒ x = -8

 

or

 

2x - 7 = 0 ⇒ x = 7/2

 

Work the others the same way.
