What is the expression in factored form? 2x^2+16x+24

Divide 2 out of all terms since it is a common multiple.

2 (x²+8x+12) = 0

now factor; two common multiples of 12 that add up

to 8 are 6 & 2.

2 (x+6) (x+2) = 0; then,

2=0 ... invalid answer; ignore this.

x+6=0; then x = - 6

x+2=0; then x = - 2

x = - 6, - 2
