Factor the expression completely.
8x2 - 18

2 ( 2x-3) (2x+3)

Step-by-step explanation:

8x^2 - 18

Factor out a 2

2(4x^2 -9)

Inside the parentheses is the difference of squares

2 ((2x)^2 - 3^2)

We know the difference of squares is (a^2 -b^2) = (a-b)(a+b)

2 ( 2x-3) (2x+3)

there will be 35 boys in each team. : )

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
