SAT Mathematics Practice Test 7

Applying the distributive property to the expression yields 7532 + 100y 2 + 100y 2 − 1100. Then adding together7532 + $100{\mathit{y}}^2$ and $100{\mathit{y}}^2$ − 1100 and collecting like terms results in $200{\mathit{y}}^2$ + 6432. This is written in the form $\mathit{a}{\mathit{y}}^2+\mathit{b}$, where a = 200 and b = 6432. Therefore a + b = 200 + 6432 = 6632.
