Solve 13az^2+(+4az^2)+(-20az^2)+(+5az^2)

$$13 a z ^ { 2 } + ( + 4 a z ^ { 2 } ) + ( - 20 a z ^ { 2 } ) + ( + 5 a z ^ { 2 } )$$

Evaluate

$$2az^{2}$$

Solution Steps

Combine 13az^{2} and 4az^{2} to get 17az^{2}.

$$17az^{2}-20az^{2}+5az^{2}$$

Combine 17az^{2} and -20az^{2} to get -3az^{2}.

$$-3az^{2}+5az^{2}$$

Combine -3az^{2} and 5az^{2} to get 2az^{2}.

$$2az^{2}$$

Differentiate w.r.t. a

$$2z^{2}$$
