3 answers
Simplifying, we combine like terms: (-3f^2 + 8f^2) + (4f + 7f) + (-3 + 1) = 5f^2 + 11f - 2. Answer: \boxed{5f^2+11f-2}.
add or subtract. (2x^2+6x+1)+(-7x^2+2x-3)
When adding or subtracting polynomials, we combine like terms. Starting with the $x^2$ terms, we have $2x^2 + (-7x^2) = -5x^2.$ Next, adding the $x$ terms, we get $6x+2x=8x.$ Finally, adding the constants, we get $1+(-3)=-2.$ Putting everything back together, we have: $$ (2x^2+6x+1)+(-7x^2+2x-3) = -5x^2 + 8x - 2.$$ Answer: \boxed{-5x^2+8x-2}.
