How do you subtract polynomial expressions? Please use (5g^2 + 6g - 10) - (2g^2 + 2g + 9) as the example equation
(5g^2 + 6g - 10) - (2g^2 + 2g + 9) distribute the negative sign across the terms in the second set of parentheses, and we have
5g^2 + 6g - 10 - 2g^2 - 2g - 9 now, just combine like terms
[5g^2 - 2g^2] + [6g - 2g] - 10 - 9
3g^2 + 4g - 19
