expand (x^3+2x-1)(-2+3x-5x^2)

expand

(x^{3} + 2 x - 1) (- 2 + 3 x - 5 x^{2})

- 5 x^{5} + 3 x^{4} - 12 x^{3} + 11 x^{2} - 7 x + 2

Solution steps

(x^{3} + 2 x - 1) (- 2 + 3 x - 5 x^{2})

Distribute parentheses

= x^{3} (- 2) + x^{3} \cdot 3 x + x^{3} (- 5 x^{2}) + 2 x (- 2) + 2 x \cdot 3 x + 2 x (- 5 x^{2}) - 1 \cdot (- 2) - 1 \cdot 3 x - 1 \cdot (- 5 x^{2})

Simplify

x^{3} (- 2) + x^{3} \cdot 3 x + x^{3} (- 5 x^{2}) + 2 x (- 2) + 2 x \cdot 3 x + 2 x (- 5 x^{2}) - 1 \cdot (- 2) - 1 \cdot 3 x - 1 \cdot (- 5 x^{2}) : - 5 x^{5} + 3 x^{4} - 12 x^{3} + 11 x^{2} - 7 x + 2

= - 5 x^{5} + 3 x^{4} - 12 x^{3} + 11 x^{2} - 7 x + 2

f (x) - 4 x + 6

\frac{( 2 ^{x + 1} + 2 ^{x} )}{( 2 ^{x + 1} - 2 ^{x} )}

(a) x^{2} + 11 x + 28

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

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