Match each quadratic equation with its solution set.

( 8 , - 8)  => x² - 55 = 9

( 4 , - 4)  =>  2x² - 32 = 0

(5 , - 5) => 4x² - 100 = 0

(11 , - 11) => x² - 140 = -19

( 3, - 3) =>  2x² - 18 = 0

Step-by-step explanation:

1)

x = ( 4 , - 4)

2)

x = ( 5 , - 5 )

3)

x= ( 8 , - 8)

4)

x = ( 11  , -11)

5)

x = ( 3 , - 3)

a) 7x=7
