(x^2 + 3x - 4) + (-7x^2 + 3x + 2)
Distributive a positive 1 to each term in second set of parentheses.
x^2 + 3x - 4 - 7x^2 + 3x + 2
Combine like terms.
-6x^2 + 6x - 2 is the sum of both equations.
It is, however, possible to simplify the answer further.
Extract the GCF of each term, which is -2.
-2(3x^2 - 3x + 1) is the fully simplified answer, in case you need it.
