solve the equation by factoring. show work
2x^2 = 7x+15
-------------
2x%5E2+-+7x+-+15+=+0
-----------
The factors will be
(x + a)*(2x + b)
-----
The product of a*b = -15, so the signs will be different.
One plus, one minus.
a & b are 1 & 15 or 3 & 5, plus or minus.
Try combinations until you find it.
That's how it's done.
