expand (sqrt(x)-x+2)^2

expand

(x - x + 2)^{2}

x^{2} - 3 x - 2 x x + 4 x + 4

Solution steps

(x - x + 2)^{2}

Apply exponent rule:

a^{b + c} = a^{b} \cdot a^{c}

(x - x + 2)^{2} = (x - x + 2) (x - x + 2)

= (x - x + 2) (x - x + 2)

Distribute parentheses

= x x + x (- x) + x \cdot 2 - x x - x (- x) - x \cdot 2 + 2 x + 2 (- x) + 2 \cdot 2

Simplify

x x + x (- x) + x \cdot 2 - x x - x (- x) - x \cdot 2 + 2 x + 2 (- x) + 2 \cdot 2 : x^{2} - 3 x - 2 x x + 4 x + 4

= x^{2} - 3 x - 2 x x + 4 x + 4

x (y^{2} - 1) - y (x^{2} - 1) y^{'} (x)

\frac{d}{d t} ((Q (t)) k (Q (t) - 70))

(3 x + 2 i)^{2}

\frac{2 x + 5}{( x ^{2} + 2 ) ( x + 1 ) ^{''}}

(2 x + 1)!
