solvefor x,(x+a)^2+y^2=a^2

解答

求解

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

解答

x = a^{2} - y^{2} - a, x = - a^{2} - y^{2} - a

求解步骤

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

将

y^{2}

到右边

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

对于

(g (x))^{2} = f (a)

解为

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

解

x + a = a^{2} - y^{2} : x = a^{2} - y^{2} - a

解

x + a = - a^{2} - y^{2} : x = - a^{2} - y^{2} - a

二次方程组的解是:

x = a^{2} - y^{2} - a, x = - a^{2} - y^{2} - a

solvefor x,x(x+4y)-3=0

so l v e f or x, x (x + 4 y) - 3 = 0

solvefor y,x= 1/4 py^2

so l v e f or y, x = \frac{1}{4} p y^{2}

x^{2} + 15 x - 5400 = 0

x^{2} + 2 n + 4 = 0

17a^2-22a+10=10a^2+2a+7

17 a^{2} - 22 a + 10 = 10 a^{2} + 2 a + 7
