expand (2x-1)(2x^2-9x+3)

expand

(2 x - 1) (2 x^{2} - 9 x + 3)

4 x^{3} - 20 x^{2} + 15 x - 3

Solution steps

(2 x - 1) (2 x^{2} - 9 x + 3)

Distribute parentheses

= 2 x \cdot 2 x^{2} + 2 x (- 9 x) + 2 x \cdot 3 - 1 \cdot 2 x^{2} - 1 \cdot (- 9 x) - 1 \cdot 3

Simplify

2 x \cdot 2 x^{2} + 2 x (- 9 x) + 2 x \cdot 3 - 1 \cdot 2 x^{2} - 1 \cdot (- 9 x) - 1 \cdot 3 : 4 x^{3} - 20 x^{2} + 15 x - 3

= 4 x^{3} - 20 x^{2} + 15 x - 3

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

1 \frac{1}{2} \times 2

+ 5 b + b c

(2 e^{t})^{2}

(x^{- 3} + y^{3})^{- 7}
