Which technique is most appropriate to use to solve each equation. (x+3) (x+2)=0

Set (x+3) to 0. X+3=0. X=-3

Set (x+2) to 0 X+2=0. X=-2

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
