Question
find (f+g)(x) and (f-g)(x)
f(x)=4x^2+7x-5 and g(x)=-9x^2+5x

Answer
Since f(x) = 4x + 7x - 5 and g(x) = -9x + 5x,
we can find the sum and difference of the two.

It can be seen that (f+g)(x) = 4x + 7x - 5 - 9x + 5x.
Grouping terms together gives (4-9)x + (7+5)x - 5 = -5x + 12x - 5.

It can be seen that (f-g)(x) = 4x + 7x - 5 + 9x - 5x.
Grouping terms together gives (4+9)x + (7-5)x - 5 = 13x + 2x - 5.
