expand (x+2)(3x^2+5x+10)

expand

(x + 2) (3 x^{2} + 5 x + 10)

3 x^{3} + 11 x^{2} + 20 x + 20

Solution steps

(x + 2) (3 x^{2} + 5 x + 10)

Distribute parentheses

= x \cdot 3 x^{2} + x \cdot 5 x + x \cdot 10 + 2 \cdot 3 x^{2} + 2 \cdot 5 x + 2 \cdot 10

Simplify

x \cdot 3 x^{2} + x \cdot 5 x + x \cdot 10 + 2 \cdot 3 x^{2} + 2 \cdot 5 x + 2 \cdot 10 : 3 x^{3} + 11 x^{2} + 20 x + 20

= 3 x^{3} + 11 x^{2} + 20 x + 20

40 \times 3

16 x + 56

- \frac{2}{1 + \frac{1}{s} + \frac{2 s}{2 s + 1}}

(x^{4} + 5 x + 9 x^{2}) - (x^{4} + 4 x^{2} - 4)

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