solvefor x,h(x)^2=(5)^2+(12)^2+(x)^2

解答

求解

x, h (x)^{2} = (5)^{2} + (12)^{2} + (x)^{2}

解答

x = \frac{13}{h - 1}, x = - \frac{13}{h - 1}; h \neq = 1

求解步骤

h x^{2} = (5)^{2} + (12)^{2} + x^{2}

展开

5^{2} + 1 2^{2} + x^{2} : x^{2} + 169

h x^{2} = x^{2} + 169

将

x^{2}

para o lado esquerdo

h x^{2} - x^{2} = 169

分解

h x^{2} - x^{2} : x^{2} (h - 1)

x^{2} (h - 1) = 169

两边除以

h - 1; h \neq = 1

x^{2} = \frac{169}{h - 1}; h \neq = 1

对于

x^{2} = f (a)

解为

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

x = \frac{169}{h - 1}, x = - \frac{169}{h - 1}; h \neq = 1

化简

\frac{169}{h - 1} : \frac{13}{h - 1}

化简

- \frac{169}{h - 1} : - \frac{13}{h - 1}

x = \frac{13}{h - 1}, x = - \frac{13}{h - 1}; h \neq = 1

4x^2-y^2-20x-10y-25=0

4 x^{2} - y^{2} - 20 x - 10 y - 25 = 0

18x^2-32y^2-108y-128x-254=0^2

18 x^{2} - 32 y^{2} - 108 y - 128 x - 254 = 0^{2}

(x^2)/5-(y^2)/1 =1

\frac{x ^{2}}{5} - \frac{y ^{2}}{1} = 1

3y^2-x^2+18y+4x+28=0

3 y^{2} - x^{2} + 18 y + 4 x + 28 = 0

(50)/(x+y)+8/(x-y)=7

\frac{50}{x + y} + \frac{8}{x - y} = 7
