expand (3x-5y+2z)(3x+8y)

expand

(3 x - 5 y + 2 z) (3 x + 8 y)

9 x^{2} + 9 x y - 40 y^{2} + 6 x z + 16 yz

Solution steps

(3 x - 5 y + 2 z) (3 x + 8 y)

Distribute parentheses

= 3 x \cdot 3 x + 3 x \cdot 8 y - 5 y \cdot 3 x - 5 y \cdot 8 y + 2 z \cdot 3 x + 2 z \cdot 8 y

Simplify

3 x \cdot 3 x + 3 x \cdot 8 y - 5 y \cdot 3 x - 5 y \cdot 8 y + 2 z \cdot 3 x + 2 z \cdot 8 y : 9 x^{2} + 9 x y - 40 y^{2} + 6 x z + 16 yz

= 9 x^{2} + 9 x y - 40 y^{2} + 6 x z + 16 yz

1.0 3^{20}

4 (x - 8)

3 (m - z) + 5 (2 m - z)

\frac{5 ^{2}}{5 ^{23}}

(- 4 a + 9) - (a + 3)
