Solution steps

(6 - 54) (- 57)

Apply rule:

a (- b) = - ab

(6 - 54) (- 57) = - 6 - 54 \cdot 57

= - 6 - 54 \cdot 57

- 54 = 3 - 6

= - 6 \cdot 3 - 6 \cdot 57

Multiply the numbers:

- 6 \cdot 3 \cdot 5 = - 90

= - 90 - 6 7

= - 907 - 6

- 6 = 6 i

= - 9076 i

76 = 42

= - 9042 i

- \frac{1}{2} + i \frac{3}{2}

\frac{4 ^{8}}{4 ^{- 4}}

\frac{x - 9}{x ^{2} - 17 x + 72} \cdot \frac{x ^{2} - 64}{6 x + 48}

(- 66) (10 - 30)

36 x^{4} - 28 x^{2}
