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

expand

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

2 x^{3} - 15 x^{2} + 11 x - 2

Solution steps

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

Distribute parentheses

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

Simplify

2 x x^{2} + 2 x (- 7 x) + 2 x \cdot 2 - 1 \cdot x^{2} - 1 \cdot (- 7 x) - 1 \cdot 2 : 2 x^{3} - 15 x^{2} + 11 x - 2

= 2 x^{3} - 15 x^{2} + 11 x - 2

(\frac{1}{2} y^{2} - 3)^{2}

(x + 2) (x + 6)

10 98 x^{4} + 5 x^{2} 128

\frac{1500}{0}

6 7 \cdot (1) + 9
