Solve y=left(-3^2-3right)^2-left(-3^2-2right)^2

$$y = { \left(- { 3 }^{ 2 } -3 \right) }^{ 2 } - { \left(- { 3 }^{ 2 } -2 \right) }^{ 2 }$$

Solve for y

$$y=23$$

Steps for Solving Linear Equation

Calculate 3 to the power of 2 and get 9.

$$y=\left(-9-3\right)^{2}-\left(-3^{2}-2\right)^{2}$$

Subtract 3 from -9 to get -12.

$$y=\left(-12\right)^{2}-\left(-3^{2}-2\right)^{2}$$

Calculate -12 to the power of 2 and get 144.

$$y=144-\left(-3^{2}-2\right)^{2}$$

Calculate 3 to the power of 2 and get 9.

$$y=144-\left(-9-2\right)^{2}$$

Subtract 2 from -9 to get -11.

$$y=144-\left(-11\right)^{2}$$

Calculate -11 to the power of 2 and get 121.

$$y=144-121$$

Subtract 121 from 144 to get 23.

$$y=23$$

Assign y

$$y≔23$$
