Question

Find the roots of x(x+4)=12

Answer 1

Answer:

x(x+4) =12

x²+4x=12

x²+4x-12=0

x²+6x-2x-12=0

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

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

so then,

x= -6 Or x=2

ans.......

Answer 2

Answer:

➡️ x ( x + 4 ) = 12

= x² + 4x = 12

= x² + 4x - 12 = 0

= x² + 6x - 2x - 12 = 0

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

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

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

x = - 6 (or) x = 2

Roots of given quadratic equation is -6 , 2
