expand (2a^2+7a-10)(a-5)

expand

(2 a^{2} + 7 a - 10) (a - 5)

2 a^{3} - 3 a^{2} - 45 a + 50

Solution steps

(2 a^{2} + 7 a - 10) (a - 5)

Distribute parentheses

= 2 a^{2} a + 2 a^{2} (- 5) + 7 aa + 7 a (- 5) - 10 a - 10 (- 5)

Simplify

2 a^{2} a + 2 a^{2} (- 5) + 7 aa + 7 a (- 5) - 10 a - 10 (- 5) : 2 a^{3} - 3 a^{2} - 45 a + 50

= 2 a^{3} - 3 a^{2} - 45 a + 50

(x + 7) (x + 8)

13 \times 13

\frac{7}{28}

\frac{x ^{2} + 8 x + 15}{x + 3}

(x^{2} - 3 y)^{3}
