Question

Find the nature of the roots of the equation X² + 8x + 16 = 0.​

Answer 1

Given equation is x2−8x+16=0

Given equation is x2−8x+16=0Discriminant is (−8)2−4×1×16=64−64=0

Given equation is x2−8x+16=0Discriminant is (−8)2−4×1×16=64−64=0Since the discriminant is zero, the quadratic equation has equal and real roots.

Answer 2

Given equation is x^2−8x+16=0

Discriminant is (−8) ^2 −4×1×16=64−64=0

Since the discriminant is zero, the quadratic equation has equal and real roots.
