Question

find the discriminant of 4x2+4ax-(a2-b2)=0​

Answer 1

Answer:

If it helps mark me as brainliest.

Step-by-step explanation:

$p(x) = 8 + 4ax - ( {a}^{2} - {b}^{2} ) \\ therefore \\ \: discriminant = {(4a)}^{2} - 4 \times 8 \times - ( {a}^{2} - {b}^{2} ) \\ = 16 {a}^{2} + 32( {a}^{2} - {b}^{2} ) \\ = 48 {a}^{2} - 32 {b}^{2}$
