Can someone check my expansion of (x+10)(2x-3)

OpenStudy (homeworksucks):

I got \[2x^2+17x-30=54\]

OpenStudy (homeworksucks):

The problem was equal to 54 and moved 54 over

OpenStudy (homeworksucks):

and got \[2x^2+17x+24=0\] which seems unfactorable...

@Directrix

OpenStudy (anonymous):

not 24 it is -84

OpenStudy (homeworksucks):

Ohhhhhh

OpenStudy (homeworksucks):

Thanks

OpenStudy (anonymous):

How did you get -84? I got 24 also

OpenStudy (homeworksucks):

Subtract 54 from both ides, not add it

OpenStudy (homeworksucks):

*sides

@Homeworksucks See if (x + 12) is a factor.
