simplify (x+2y)(x+2y+2)-8

simplify

(x + 2 y) (x + 2 y + 2) - 8

x^{2} + 4 x y + 2 x + 4 y^{2} + 4 y - 8

Solution steps

(x + 2 y) (x + 2 y + 2) - 8

Distribute parentheses

= xx + x \cdot 2 y + x \cdot 2 + 2 y x + 2 y \cdot 2 y + 2 y \cdot 2 - 8

Simplify

xx + x \cdot 2 y + x \cdot 2 + 2 y x + 2 y \cdot 2 y + 2 y \cdot 2 : x^{2} + 4 x y + 2 x + 4 y^{2} + 4 y

= x^{2} + 4 x y + 2 x + 4 y^{2} + 4 y - 8

- 3 (y - 5)

\frac{( x ^{3} - 4 x )}{( - 4 x ^{2} + 12 x )}

2 r^{2} - 5 x^{1} + 6 \cdot 3 x^{4} - 5 x^{3} - 6 x^{2} + 4 x - 3

(\frac{3 x - 5 - 1}{( 3 x - 5 )})^{5}

\frac{x ^{2}}{2} + \frac{10}{3} x + 2
