Solve -3=a(0+3)^2-12

$$- 3 = a ( 0 + 3 ) ^ { 2 } - 12$$

Solve for a

$$a=1$$

Steps for Solving Linear Equation

Add 0 and 3 to get 3.

$$-3=a\times 3^{2}-12$$

Calculate 3 to the power of 2 and get 9.

$$-3=a\times 9-12$$

Swap sides so that all variable terms are on the left hand side.

$$a\times 9-12=-3$$

Add 12 to both sides.

$$a\times 9=-3+12$$

Add -3 and 12 to get 9.

$$a\times 9=9$$

Divide both sides by 9.

$$a=\frac{9}{9}$$

Divide 9 by 9 to get 1.

$$a=1$$
