You can put this solution on YOUR website! So, if you have:
Subtract -5a^2-5a+7 from -8a^2-5a+4
.
This would be equivalent to:
(-8a^2-5a+4) - (-5a^2-5a+7)
Start by distributing the negative sign (-) to terms inside the parenthesis:
(-8a^2-5a+4) + 5a^2+5a-7
-8a^2-5a+4 + 5a^2+5a-7
Combine like-terms:
(-8a^2+5a^2)+(-5a+5a)+(4-7)
(-3a^2)+(0)+(-3)
Resulting in:
-3a^2 - 3
