Question

Find the roots of quadratic equation of
factorisation method x²+7x+12=0​

Answer 1

Answer:

For discriminant method we will apply the general formula x=−b±√b2−4ac2a for any quadratic equation ax2+bx+c=0. Hence, the two roots of the given quadratic equation are -3 and -4.

Answer 2

Answer:

-4 and -3

Step-by-step explanation:

x²+7x+12=0

x²+4x+3x+12=0

x(x+4)+3(x+4)=0

(x+4)(x+3) =0

hence , x = -4 and -3
