Solve (-20)+(2(-20)^2-4(49)(12))div2(449)

$$( - 20 ) + ( 2 ( - 20 ) ^ { 2 } - 4 ( 49 ) ( 12 ) ) \div 2 ( 449 )$$

Evaluate

$$-348444$$

Solution Steps

Calculate -20 to the power of 2 and get 400.

$$-20+\frac{2\times 400-4\times 49\times 12}{2}\times 449$$

Multiply 2 and 400 to get 800.

$$-20+\frac{800-4\times 49\times 12}{2}\times 449$$

Multiply 4 and 49 to get 196.

$$-20+\frac{800-196\times 12}{2}\times 449$$

Multiply 196 and 12 to get 2352.

$$-20+\frac{800-2352}{2}\times 449$$

Subtract 2352 from 800 to get -1552.

$$-20+\frac{-1552}{2}\times 449$$

Divide -1552 by 2 to get -776.

$$-20-776\times 449$$

Multiply -776 and 449 to get -348424.

$$-20-348424$$

Subtract 348424 from -20 to get -348444.

$$-348444$$

Factor
