solvefor x,fx=x^2sqrt(x)

解答

求解

x, f x = x^{2} x

解答

x = 0, x = 3 f^{2} {f \geq 0}

求解步骤

f x = x^{2} x

将

x^{2} x

para o lado esquerdo

f x - x^{2} x = 0

因式分解

f x - x^{2} x : x (f - x x)

x (f - x x) = 0

使用零因数法则： If

ab = 0

then

a = 0

or

b = 0

x = 0 or f - x x = 0

解

f - x x = 0 : x = 3 f^{2} {f \geq 0}

x = 0, x = 3 f^{2} {f \geq 0}

验证解:

x = 0

真

, x = 3 f^{2} {f \geq 0}

解为

x = 0, x = 3 f^{2} {f \geq 0}

流行的例子

x = - 4 x + 5

x^{4} = 2

24.1=14(t+5)^{1/3}

24.1 = 14 (t + 5)^{\frac{1}{3}}

2/(3\sqrt[3]{x-2)}=0

\frac{2}{3 3 x - 2} = 0

sqrt(14x+49)=x+7

14 x + 49 = x + 7
