7-56.

Integrate.

1. $\int(3x − 5)^2dx$

Before integrating, expand the integrand.

1. $\int _ { - 3 } ^ { 3 } 9 \operatorname { sin } ( \pi x ) d x$

Consider the symmetry of the integrand. Can you integrate on these bounds without a calculator?

1. $\int(6m^{−7} + 2)dx$
$m$ is a constant

$6m^{−7}$ is a constant, just like $2$ is a constant.

$(6m^{−7} + 2)x + C$
