Solve (10*2+3)(3*2-7)-(3*2-7)^2

$$( 10 \times 2 + 3 ) ( 3 \times 2 - 7 ) - ( 3 \times 2 - 7 ) ^ { 2 }$$

Evaluate

$$-24$$

Solution Steps

Multiply 10 and 2 to get 20.

$$\left(20+3\right)\left(3\times 2-7\right)-\left(3\times 2-7\right)^{2}$$

Add 20 and 3 to get 23.

$$23\left(3\times 2-7\right)-\left(3\times 2-7\right)^{2}$$

Multiply 3 and 2 to get 6.

$$23\left(6-7\right)-\left(3\times 2-7\right)^{2}$$

Subtract 7 from 6 to get -1.

$$23\left(-1\right)-\left(3\times 2-7\right)^{2}$$

Multiply 23 and -1 to get -23.

$$-23-\left(3\times 2-7\right)^{2}$$

Multiply 3 and 2 to get 6.

$$-23-\left(6-7\right)^{2}$$

Subtract 7 from 6 to get -1.

$$-23-\left(-1\right)^{2}$$

Calculate -1 to the power of 2 and get 1.

$$-23-1$$

Subtract 1 from -23 to get -24.

$$-24$$

Factor
