Solve y=2^4-9(2)^2-4(2)+12

$$y = 2 ^ { 4 } - 9 ( 2 ) ^ { 2 } - 4 ( 2 ) + 12$$

Solve for y

$$y=-16$$

Steps for Solving Linear Equation

Calculate 2 to the power of 4 and get 16.

$$y=16-9\times 2^{2}-4\times 2+12$$

Calculate 2 to the power of 2 and get 4.

$$y=16-9\times 4-4\times 2+12$$

Multiply 9 and 4 to get 36.

$$y=16-36-4\times 2+12$$

Subtract 36 from 16 to get -20.

$$y=-20-4\times 2+12$$

Multiply 4 and 2 to get 8.

$$y=-20-8+12$$

Subtract 8 from -20 to get -28.

$$y=-28+12$$

Add -28 and 12 to get -16.

$$y=-16$$

Assign y

$$y≔-16$$
