Question

Solve 2x^2 = −10x by factoring
possible answers:
x = 2, x = −5

x = 2, x = 5

x = 0, x = 5

x = 0, x = −5

Answer 1

First get the -10x on the left by adding it to both sides

Answer 2

ok. then?

Answer 3

You have 2x^2+10x=0 right?

Answer 4

What can you factor out of 2x^2+10x?

Answer 5

2x

Answer 6

Yep, so you get 2x(x+5)=0

Answer 7

So 2x=0 and x+5=0

solve for x in both of those

Answer 8

ok. so x=0 and x=-5?

Answer 9

Yep thats correct

Answer 10

ok thanks:)

Answer 11

You're welcome
