expand (Cx+D)(x^2+sqrt(2)x+1)

expand

(C x + D) (x^{2} + 2 x + 1)

C x^{3} + 2 C x^{2} + C x + x^{2} D + 2 D x + D

Solution steps

(C x + D) (x^{2} + 2 x + 1)

Distribute parentheses

= C x x^{2} + C x 2 x + C x \cdot 1 + D x^{2} + D 2 x + D \cdot 1

Simplify

C x x^{2} + C x 2 x + C x \cdot 1 + D x^{2} + D 2 x + D \cdot 1 : C x^{3} + 2 C x^{2} + C x + x^{2} D + 2 D x + D

= C x^{3} + 2 C x^{2} + C x + x^{2} D + 2 D x + D
