expand (2x^2-x+1)(x+4)

expand

(2 x^{2} - x + 1) (x + 4)

2 x^{3} + 7 x^{2} - 3 x + 4

Solution steps

(2 x^{2} - x + 1) (x + 4)

Distribute parentheses

= 2 x^{2} x + 2 x^{2} \cdot 4 - xx - x \cdot 4 + 1 \cdot x + 1 \cdot 4

Simplify

2 x^{2} x + 2 x^{2} \cdot 4 - xx - x \cdot 4 + 1 \cdot x + 1 \cdot 4 : 2 x^{3} + 7 x^{2} - 3 x + 4

= 2 x^{3} + 7 x^{2} - 3 x + 4

(4 y^{- 2}) (8 y^{4})

\frac{1}{6} (\frac{3}{5} x + 18)
