expand (x^2+3x-40)(x-5)

expand

(x^{2} + 3 x - 40) (x - 5)

x^{3} - 2 x^{2} - 55 x + 200

Solution steps

(x^{2} + 3 x - 40) (x - 5)

Distribute parentheses

= x^{2} x + x^{2} (- 5) + 3 xx + 3 x (- 5) - 40 x - 40 (- 5)

Simplify

x^{2} x + x^{2} (- 5) + 3 xx + 3 x (- 5) - 40 x - 40 (- 5) : x^{3} - 2 x^{2} - 55 x + 200

= x^{3} - 2 x^{2} - 55 x + 200

3 x^{2} + 5 x^{3}

\frac{x - 1}{( 1 - x ) x}

(- 38) - 30

y^{4} - 121

3 + (- 3)^{- 2} - (9 + 7)^{0}
