Homework Help: math

Trying to factor 2 equations
3x2+9x-30
4x2-4x-48

I assume you mean 3x² + 9x - 30

which on this board most people write as 3x^2 ...

=3(x^2 + 3x - 10)
=3(x+5)(x-2)

do the same thing for your second question, factor out the 4 first, then it's easy
Let me know what you got

4(x-4)(x+3)?

yup!

Thanks
