Question

Determine whether the given value of variable is the roots of given quadratic equation.
x^2+4x-5=0,x=-1​

Answer 1

Answer is No.

Step-by-step explanation:

${x}^{2} + 4x - 5 = 0$

x=-1

Put it in above equation:

(-1)^2 + 4(-1) - 5 = 0

1-4-5=0

-8 which is not equal to zero

Thus, x=-1 is not the factor of given equation.

Its factors be x=-5, and x=1
