expand (x^2+3x+3)(-2x^2-x+6)

expand

(x^{2} + 3 x + 3) (- 2 x^{2} - x + 6)

- 2 x^{4} - 7 x^{3} - 3 x^{2} + 15 x + 18

Solution steps

(x^{2} + 3 x + 3) (- 2 x^{2} - x + 6)

Distribute parentheses

= x^{2} (- 2 x^{2}) + x^{2} (- x) + x^{2} \cdot 6 + 3 x (- 2 x^{2}) + 3 x (- x) + 3 x \cdot 6 + 3 (- 2 x^{2}) + 3 (- x) + 3 \cdot 6

Simplify

x^{2} (- 2 x^{2}) + x^{2} (- x) + x^{2} \cdot 6 + 3 x (- 2 x^{2}) + 3 x (- x) + 3 x \cdot 6 + 3 (- 2 x^{2}) + 3 (- x) + 3 \cdot 6 : - 2 x^{4} - 7 x^{3} - 3 x^{2} + 15 x + 18

= - 2 x^{4} - 7 x^{3} - 3 x^{2} + 15 x + 18

(3 + 11 i) + (- 2 + 3 i)

(2 - 3 i)^{- 1}

\frac{- x y ^{2}}{2 y}

\frac{2}{3 + 1}
