expand 2(8-2x-2y)^2

expand

2 (8 - 2 x - 2 y)^{2}

16 x y - 64 x + 8 x^{2} - 64 y + 8 y^{2} + 128

Solution steps

2 (8 - 2 x - 2 y)^{2}

(8 - 2 x - 2 y)^{2} = 8 x y - 32 x + 4 x^{2} - 32 y + 4 y^{2} + 64

= 2 (4 x^{2} + 8 x y - 32 x + 4 y^{2} + 64 - 32 y)

Distribute parentheses

= 2 \cdot 8 x y + 2 (- 32 x) + 2 \cdot 4 x^{2} + 2 (- 32 y) + 2 \cdot 4 y^{2} + 2 \cdot 64

Apply minus-plus rules

+ (- a) = - a

= 2 \cdot 8 x y - 2 \cdot 32 x + 2 \cdot 4 x^{2} - 2 \cdot 32 y + 2 \cdot 4 y^{2} + 2 \cdot 64

Simplify

2 \cdot 8 x y - 2 \cdot 32 x + 2 \cdot 4 x^{2} - 2 \cdot 32 y + 2 \cdot 4 y^{2} + 2 \cdot 64 : 16 x y - 64 x + 8 x^{2} - 64 y + 8 y^{2} + 128

= 16 x y - 64 x + 8 x^{2} - 64 y + 8 y^{2} + 128

(x - 6) (x + 4)

\frac{\frac{m}{5}}{4} a (3, - 4)

, (- 2 y^{2} - 3 y + 5) - (- y^{2} + 4 y + 2)

\frac{( 5 x ^{2} + 3 x ^{3} ) ^{7}}{7}

(x + 3 - 2) (x + 3 + 2)
