guuh, I've been working on this problem forever and can't get it.

Find the area of the region bounded by the graphs f(x) = -x^2 + 7x + 20 and g(x) = x^2 + 5x - 40

To get the left and right x values

I do f(x) = g(x)

x^2 + 7x + 20 = x^2 + 5x - 40

2x^2 - 2x - 60 = 0

but then I'm stuck

... I think i know what to do once I get the values though
