expand (3x+2+5y)(3x+2-5y)

expand

(3 x + 2 + 5 y) (3 x + 2 - 5 y)

9 x^{2} + 12 x - 25 y^{2} + 4

Solution steps

(3 x + 2 + 5 y) (3 x + 2 - 5 y)

Distribute parentheses

= 3 x \cdot 3 x + 3 x \cdot 2 + 3 x (- 5 y) + 2 \cdot 3 x + 2 \cdot 2 + 2 (- 5 y) + 5 y \cdot 3 x + 5 y \cdot 2 + 5 y (- 5 y)

Simplify

3 x \cdot 3 x + 3 x \cdot 2 + 3 x (- 5 y) + 2 \cdot 3 x + 2 \cdot 2 + 2 (- 5 y) + 5 y \cdot 3 x + 5 y \cdot 2 + 5 y (- 5 y) : 9 x^{2} + 12 x - 25 y^{2} + 4

= 9 x^{2} + 12 x - 25 y^{2} + 4

(3 x + 3) (x + 2)

\frac{- 1}{e}

1 - \frac{3}{9}

(\frac{2}{2})^{6}

\frac{4 ^{6}}{4 ^{3}}
