(6a^2-a^3b^2+11b^3)-(5a^3b^2-4a^2+3b^2-10a) a. What is the coefficient of b^2?
To find the coefficient of b^2, we need to combine all the terms that contain b^2 and eliminate everything else.
From the given expression, we can see that the terms which contain b^2 are -a^3b^2 and 3b^2.
Therefore, the coefficient of b^2 is (-a^3b^2) + (3b^2) = -a^3b^2 + 3b^2 = b^2(-a^3 + 3).
Thus, the coefficient of b^2 is -a^3 + 3.
