Solve A=1/4((4+7)^2-(4-7)^2)

$$A = \frac { 1 } { 4 } ( ( 4 + 7 ) ^ { 2 } - ( 4 - 7 ) ^ { 2 } )$$

Solve for A

$$A=28$$

Steps for Solving Linear Equation

Add 4 and 7 to get 11.

$$A=\frac{1}{4}\left(11^{2}-\left(4-7\right)^{2}\right)$$

Calculate 11 to the power of 2 and get 121.

$$A=\frac{1}{4}\left(121-\left(4-7\right)^{2}\right)$$

Subtract 7 from 4 to get -3.

$$A=\frac{1}{4}\left(121-\left(-3\right)^{2}\right)$$

Calculate -3 to the power of 2 and get 9.

$$A=\frac{1}{4}\left(121-9\right)$$

Subtract 9 from 121 to get 112.

$$A=\frac{1}{4}\times 112$$

Multiply \frac{1}{4} and 112 to get 28.

$$A=28$$

Assign A

$$A≔28$$
