Question

What are the zeros of the expression (x-5)(2x+7)

Answer 1

5, -7/2

Explanation:

`x - 5 = 0 = 5\\\\2x + 7 = 0\\2x + -7 = 0\\(2x)/(2) = (-7)/(2)\\ x = (-7)/(2)\\x = -(7)/(2)`

Thus,

x = 5

x = -7/2

Answer 2

The zeros are x =5, -7/2

Explanation:

To find the zeros, set the expression equal to zero

(x-5)(2x+7) =0

Using the zero product property

(x-5)=0 (2x+7)=0

Solve each equation

x=5 2x = -7

x=5 x = -7/2

The zeros are x =5, -7/2
