expand (x^2-12x+27)(x-9)

expand

(x^{2} - 12 x + 27) (x - 9)

x^{3} - 21 x^{2} + 135 x - 243

Solution steps

(x^{2} - 12 x + 27) (x - 9)

Distribute parentheses

= x^{2} x + x^{2} (- 9) - 12 xx - 12 x (- 9) + 27 x + 27 (- 9)

Simplify

x^{2} x + x^{2} (- 9) - 12 xx - 12 x (- 9) + 27 x + 27 (- 9) : x^{3} - 21 x^{2} + 135 x - 243

= x^{3} - 21 x^{2} + 135 x - 243

(2 x^{2} - \frac{1}{x})^{5}

(3 a + 7 b - 9) - (5 a + 9 b + 21)

(2 x^{- 2})^{- 5}

26 + 26

12 x - 28 y + 52
