solvefor x,x^2-y^4=2035

解答

求解

x, x^{2} - y^{4} = 2035

x = 2035 + y^{4}, x = - 2035 + y^{4}

求解步骤

x^{2} - y^{4} = 2035

将

y^{4}

到右边

x^{2} = 2035 + y^{4}

对于

x^{2} = f (a)

解为

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

x = 2035 + y^{4}, x = - 2035 + y^{4}

(x - b) (x - c) + (x - c) (x - a) + (x - a) (x - b) = 0

so l v e f or x, 15 (2 x^{2} - y^{2}) = 7 x y

(3 k + 1) x^{2} + (2 k + 2) x + k = 0

(6 x + 2)^{2} = 16

\frac{( x + 2 ) ^{2} - ( 2 x + 11 )}{3} = 3
