expand (x-3)(-x^2-x+9)

expand

(x - 3) (- x^{2} - x + 9)

- x^{3} + 2 x^{2} + 12 x - 27

Solution steps

(x - 3) (- x^{2} - x + 9)

Distribute parentheses

= x (- x^{2}) + x (- x) + x \cdot 9 - 3 (- x^{2}) - 3 (- x) - 3 \cdot 9

Simplify

x (- x^{2}) + x (- x) + x \cdot 9 - 3 (- x^{2}) - 3 (- x) - 3 \cdot 9 : - x^{3} + 2 x^{2} + 12 x - 27

= - x^{3} + 2 x^{2} + 12 x - 27

(8 m + 7)^{2}

\frac{5 x ^{8} y ^{2}}{x ^{6} y ^{4}}
