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

根 x^2n^3+x^2m^3+m^5n^4

roo t s x^{2} n^{3} + x^{2} m^{3} + m^{5} n^{4}

(2 x + 2)^{2} + 5 = 1

x^2+26x+167.5=0

x^{2} + 26 x + 167.5 = 0

solvefor y,4xy-y-16x=5x^2

so l v e f or y, 4 x y - y - 16 x = 5 x^{2}

3 x^{2} = - 4 x + 3
