Question

find the factors of 6x²+72x+120=0​

Answer 1

6x2 - 72x + 120 = 6 • (x2 - 12x + 20)

Factoring x2 - 12x + 20

x2 - 10x - 2x - 20

(x-2) • (x-10)

x=2,x=10

Answer 2

find the factors of 6x²+72x+120=0

➡ 6x ^ 2 + 72 x + 120 =0

devide by 6 to the hole eqn

x ^ 2 + 1 2 x + 20

x ^ 2 + 10 x + 2x + 20

x( x + 10 ) + 2 ( x + 10 )

( x + 2 ) ( x + 10)

x = -2 or x = -10
