Subtract. Your answer should be a polynomial in standard form.
(-5q^2+6q+7) -(-q^2+4q)=
To subtract the polynomials, we need to distribute the negative sign to each term inside the parentheses:
(-5q^2 + 6q + 7) - (-q^2 + 4q) = -5q^2 + 6q + 7 + q^2 - 4q
Next, we can combine like terms:
= (-5q^2 + q^2) + (6q - 4q) + 7
= -4q^2 + 2q + 7
So the subtracted polynomial in standard form is -4q^2 + 2q + 7.
