Question

if roots of x2-5x+a=0 are equal then​

Answer 1

If roots are equal then d=0

Bsq - 4ac =0

(-5)sq - 4 (a)(1) =0

25 - 4a =0

25 =4a

a = 25/4

Hope it help you..

Answer 2

Heya

For real and equal roots Descrimnant = 0

Given Quadratic Equation is

x² - 5x + a = 0

It's Descrimnant is (-5)² -4(1)(a)

25 - 4a

For real and equal roots 25 - 4a = 0

25 = 4a

a = 25/4
