Question

for the equation 4x2 + 12x + 9 =0 determine the nature of the roots from their discrimination​

Answer 1

Answer:

Discriminant b² - 4ac

(12)² - 4 (4) (9)

144 - 144

0

Hence roots are real and equal

Answer 2

Answer:

Given : 4x² - 12x - 9 = 0 . Therefore, root of the given equation 4x² - 12x - 9 = 0 are real and distinct. Hence, nature of roots of the quadratic equation 4x²− 12x − 9 = 0 are real and distinct
