Thank you

Hope you understand..

Answer 2

Answer:

- 7 / 16

Step-by-step explanation :

since A and B are the zeroes :

A + B = -b/a

A + B = -3 / 2

A x B = c/a

A x B = 4 / 2 = 2

a² + b² / a²b²

( a + b )² - 2ab / (ab)²

( - 3/2)² - 2( 2 ) / 2 x 2

9 / 4 - 4 / 4 ( whole divided by 4 )

9 - 16 / 16

-7 / 16
