x^4 + y^4 = z^2无自然数解完整证明. Read Alps 22:09:14. 假设该丢番图方程有自然数解，则必然存在一组自然数x。. 、y。. 、z。. 使得z。. 是满足该方程的最小值解，即不存在另一组自然数f、g、h满足h < z。. 且还满足f^4 + g^4 = h^2. 对x。.

## Solve x2y=4, Microsoft Math Solver

2x2y=4 Geometric figure: Straight Line Slope = 1 xintercept = 2/1 = 2. yintercept = 2/1 = 2. Rearrange: Rearrange the equation by subtracting what is to the right of the

## Solve y=x^2+2x+4, Microsoft Math Solver

Swap sides so that all variable terms are on the left hand side. x^ {2}+2x=y4. Subtract 4 from both sides. x^ {2}+2x+1^ {2}=y4+1^ {2} Divide 2, the coefficient of the x term, by 2 to get 1. Then add the square of 1 to both sides of the equation. This step makes the left hand side of the equation a perfect square.

## Solve y=x^24x+4, Microsoft Math Solver

The equation is now solved. x^ {2}4x+4=y. Swap sides so that all variable terms are on the left hand side. \left (x2\right)^ {2}=y. Factor x^ {2}4x+4. In general, when x^ {2}+bx+c is a perfect square, it can always be factored as \left (x+\frac {b} {2}\right)^ {2}. \sqrt {\left (x2\right)^ {2}}=\sqrt {y}

## Solve x^2+y^2+x+y2+2xy, Microsoft Math Solver

Consider x^ {2}+y^ {2}+x+y2+2xy as a polynomial over variable x. Find one factor of the form x^ {k}+m, where x^ {k} divides the monomial with the highest power x^ {2} and m divides the constant factor y^ {2}+y2. One such factor is x+y1. Factor the polynomial by dividing it by this factor.
