化简 (sqrt(a)+sqrt(x))^2

解答

化简

(a + x)^{2}

a + 2 a x + x

求解步骤

(a + x)^{2}

使用完全平方公式:

(a + b)^{2} = a^{2} + 2 ab + b^{2}

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

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

(a)^{2} = a

(x)^{2} = x

= a + 2 a x + x

e x p an d (x cos (x) + sin (x))^{2}

e x p an d \frac{4 e ^{- 3 t}}{( s - 3 ) ( s + 1 )}

s im pl i f y (2 x + \frac{1}{x ^{2}}) (5 - x) (2 x^{5} + 1)^{3}

e x p an d \frac{2 ( - 4 x - 12 )}{x ^{2} - 12 x + 36}

e x p an d \frac{3 ( 15 + 7 5 )}{4}
