Can someone help me with factoring for a medal?

OpenStudy (anonymous):

Factor completely 2x^2 + 2x − 24.

OpenStudy (acxbox22):

first simplify it by taking out a common factor

OpenStudy (anonymous):

So 2, then?

OpenStudy (acxbox22):

yes divide the whole expression by 2 so it will be easier to factor

OpenStudy (anonymous):

Alright, so I got x^2 + x - 12

OpenStudy (acxbox22):

looks good now you look for two numbers that when multiplied together give you -12 but when added together give you 1

OpenStudy (anonymous):

Why 1?

OpenStudy (acxbox22):

1 is the coefficient for x

OpenStudy (anonymous):

Ah, okay. Give me a minute

OpenStudy (anonymous):

4 and -3?

OpenStudy (acxbox22):

yep now you put it into the blanks here |dw:1434582773871:dw|
