Question

QNO18.The roots of quadratic equation X2 + 6x + 5 = 0 are
a)( - 5 , - 1)
b)( 5, 1)
c)( -5, + 1)
d)None of these​

Answer 1

Answer:

a) (-5, -1)

Step-by-step explanation:

x² + 6x + 5 = 0

x² + 5x + x + 5 = 0

x*(x + 5) + 1*(x + 5) = 0

(x+1)(x+5) = 0

x+1 = 0

x= -1

x+5 = 0

x = -5

Hence roots are (-5, -1)
