11-10.

Expand these binomials.

1. $\quad ( a + b ) ^ { 3 }$

Review the Math Notes on the Binomial Theorem in lesson 10.3.3. Remember, you can also use Pascal's Triangle to help you here.

$\left(a + b\right)^{3} = _{3}C_{3}a^{3}b^{0} + _{3}C_{2}a^{2}b^{1} + _{3}C_{1}a^{1}b^{2} + _{3}C_{0}a^{0}b^{3}$

1. $( 2 m + 5 ) ^ { 3 }$

Use the result from part (a).
$a = 2m; b = 5$. Simplify.
