solvefor x,x*(x+1)=h(x)^2

解答

求解

x, x \cdot (x + 1) = h (x)^{2}

解答

x = 0, x = - \frac{1}{1 - h}; h \neq = 1

求解步骤

x (x + 1) = h x^{2}

将

h x^{2}

para o lado esquerdo

x (x + 1) - h x^{2} = 0

因式分解

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

x (1 + x - x h) = 0

使用零因数法则： If

ab = 0

then

a = 0

or

b = 0

x = 0 or 1 + x - x h = 0

解

1 + x - x h = 0 : x = - \frac{1}{1 - h}; h \neq = 1

二次方程组的解是:

x = 0, x = - \frac{1}{1 - h}; h \neq = 1

-x^2+2y^2-20y-6=0

- x^{2} + 2 y^{2} - 20 y - 6 = 0

((x-1)^2)/(64)-((y-2)^2)/(32)=1

\frac{( x - 1 ) ^{2}}{64} - \frac{( y - 2 ) ^{2}}{32} = 1

-x^2+9y^2-36y+27=0

- x^{2} + 9 y^{2} - 36 y + 27 = 0

((y-4}{16})^2-(\frac{x-6)/4)^2=1

(\frac{y - 4}{16})^{2} - (\frac{x - 6}{4})^{2} = 1

((x-1)^2}{49}-\frac{(y+3)^2)/9 =1

\frac{( x - 1 ) ^{2}}{49} - \frac{( y + 3 ) ^{2}}{9} = 1
