solvefor x,p(x)^2+x^2=25

解答

求解

x, p (x)^{2} + x^{2} = 25

解答

x = \frac{5}{p + 1}, x = - \frac{5}{p + 1}; p \neq = - 1

求解步骤

p x^{2} + x^{2} = 25

分解

p x^{2} + x^{2} : x^{2} (p + 1)

x^{2} (p + 1) = 25

两边除以

p + 1; p \neq = - 1

x^{2} = \frac{25}{p + 1}; p \neq = - 1

对于

x^{2} = f (a)

解为

x = f (a), - f (a)

x = \frac{25}{p + 1}, x = - \frac{25}{p + 1}; p \neq = - 1

化简

\frac{25}{p + 1} : \frac{5}{p + 1}

化简

- \frac{25}{p + 1} : - \frac{5}{p + 1}

x = \frac{5}{p + 1}, x = - \frac{5}{p + 1}; p \neq = - 1

流行的例子

x^{2} + (y - 3)^{2} = 81

(x - 5)^{2} + y^{2} = 25

4x^2-12x+4y^2+16y-5=0

4 x^{2} - 12 x + 4 y^{2} + 16 y - 5 = 0

x^{2} + y^{2} = 3 9^{2}

x^{2} + y^{2} - 72 = 0
