Question

discuss the nature of solutions of the following quadratic equations x2 + 8x + 16 = 0​

Answer 1

EXPLANATION.

Quadratic equations.

⇒ x² + 8x + 16 = 0.

As we know that,

⇒ D = Discriminant Or b² - 4ac.

⇒ D = (8)² - 4(1)(16).

⇒ D = 64 - 64.

⇒ D = 0.

Nature of roots are real and equal.

                                                                                                                   

MORE INFORMATION.

Nature of the roots of the quadratic expression.

(1) = Real and unequal, if b² - 4ac > 0.

(2) = Rational and different, if b² - 4ac is a perfect square.

(3) = Real and equal, if b² - 4ac = 0.

(4) = If D < 0 Roots are imaginary and unequal Or complex conjugate.

Answer 2

Answer:

Nature of roots are real and equal.

Step-by-step explanation:

d=b²- 4ac

= 64-4*16

= 64-64

= 0
