Solve (5x^2+68x^2)+2(+4x^2+8x^2)

$$( 5 x ^ { 2 } + 68 x ^ { 2 } ) + 2 ( + 4 x ^ { 2 } + 8 x ^ { 2 } )$$

Evaluate

$$97x^{2}$$

Solution Steps

Combine 5x^{2} and 68x^{2} to get 73x^{2}.

$$73x^{2}+2\left(4x^{2}+8x^{2}\right)$$

Combine 4x^{2} and 8x^{2} to get 12x^{2}.

$$73x^{2}+2\times 12x^{2}$$

Multiply 2 and 12 to get 24.

$$73x^{2}+24x^{2}$$

Combine 73x^{2} and 24x^{2} to get 97x^{2}.

$$97x^{2}$$

Expand
