expand (2x+1)(x^2-5x-7)

expand

(2 x + 1) (x^{2} - 5 x - 7)

2 x^{3} - 9 x^{2} - 19 x - 7

Solution steps

(2 x + 1) (x^{2} - 5 x - 7)

Distribute parentheses

= 2 x x^{2} + 2 x (- 5 x) + 2 x (- 7) + 1 \cdot x^{2} + 1 \cdot (- 5 x) + 1 \cdot (- 7)

Simplify

2 x x^{2} + 2 x (- 5 x) + 2 x (- 7) + 1 \cdot x^{2} + 1 \cdot (- 5 x) + 1 \cdot (- 7) : 2 x^{3} - 9 x^{2} - 19 x - 7

= 2 x^{3} - 9 x^{2} - 19 x - 7

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

- 5 \times 8

7 \times (- 7)

9^{l o g_{3} (4)}

60 \times 8
