expand 2(x+h-3)^2

expand

2 (x + h - 3)^{2}

4 x h + 2 x^{2} - 12 x + 2 h^{2} - 12 h + 18

Solution steps

2 (x + h - 3)^{2}

(x + h - 3)^{2} = 2 x h + x^{2} - 6 x + h^{2} - 6 h + 9

= 2 (x^{2} + 2 x h - 6 x + h^{2} + 9 - 6 h)

Distribute parentheses

= 2 \cdot 2 x h + 2 x^{2} + 2 (- 6 x) + 2 h^{2} + 2 (- 6 h) + 2 \cdot 9

Apply minus-plus rules

+ (- a) = - a

= 2 \cdot 2 x h + 2 x^{2} - 2 \cdot 6 x + 2 h^{2} - 2 \cdot 6 h + 2 \cdot 9

Simplify

2 \cdot 2 x h + 2 x^{2} - 2 \cdot 6 x + 2 h^{2} - 2 \cdot 6 h + 2 \cdot 9 : 4 x h + 2 x^{2} - 12 x + 2 h^{2} - 12 h + 18

= 4 x h + 2 x^{2} - 12 x + 2 h^{2} - 12 h + 18

\frac{- 2 x - 1}{8 x} a t (9, - 0.79)

(\forall y) (\forall z) (x + y = z)

\frac{7 u ^{4} + 3 u ^{3}}{- u ^{2}}

2 x e^{y^{2} - x^{2}} - 2 x e^{y^{2} - x^{2}} (x^{2} + y^{2})

(x^{2} - x^{4},) 2 + (y^{2} - y^{2}) 2
