Hello,
(x+2)(x+3)(x+5)=(x+2)(x-3)(x+5)
==>(x+2)(x+5)(x+3-(x-3))=0
==>(x+2)(x+5)*6=0
==>x=-2 or x=-5
Answer:
Step-by-step explanation:
you can factor this pretty straight forward
2x^2 +5x=12
2x^2 +5x-12=0
Use FOIL
(2x-3)(x-4)=0
then solve for each part separately, b/c if either side is zero the whole thing is zero
2x-3 = 0
2x = 3
x = 3/2
then
x-4=0
x = 4
