Solve 3az^2+(+4az^2)+(-20az^2)+(+5az^2)

$$3 a z ^ { 2 } + ( + 4 a z ^ { 2 } ) + ( - 20 a z ^ { 2 } ) + ( + 5 a z ^ { 2 } )$$

Evaluate

$$-8az^{2}$$

Solution Steps

Combine 3az^{2} and 4az^{2} to get 7az^{2}.

$$7az^{2}-20az^{2}+5az^{2}$$

Combine 7az^{2} and -20az^{2} to get -13az^{2}.

$$-13az^{2}+5az^{2}$$

Combine -13az^{2} and 5az^{2} to get -8az^{2}.

$$-8az^{2}$$

Differentiate w.r.t. a

$$-8z^{2}$$
