Question

Find the roots of the following quadratic equations by factorisation:x(x+4)=
12​

Answer 1

x(x+4)=12

x²+4x-12=0

x²+6x-2x-12=0

x(x+6)-2(x+6)=0

(x-2)(x+6)=0

roots :-

x-2=0

x=0+2

x=2

1st root = 2

x+6=0

x=0-6

x=-6

2nd root = -6

Answer 2

Answer:

+6 and -2 are the roots of this equation
