Question

Write the discriminant of the quadratic equation (x + 5)2 = 2(5x – 3).​

Answer 1

Answer: -124 I think..

Step-by-step explanation:

Answer 2

Answer:

Discreminant (D) = -24

Step-by-step explanation:

(x+5)² = 2(5x-3)

=> x²+2×x×5+25 = 10x-6

=> x²+10x+25-10x+6=0

=> x²+0x+6=0

Compare this with ax²+bx+c=0 we get

a = 1 , b = 0, c = 6

Discreminant (D) = b²-4ac

= 0²-4×1×6

= -24

Therefore,.

Discreminant (D) = -24
