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.

Limit with 2 variables: $\\frac{x^2y}{x^4 +y^2}$, $\\frac

$\displaystyle f(x,y)=\frac{e^{x^3y}1}{x^2+y^4}\sim\frac {x^3y}{x^2+y^4}=\frac{m^3y^7}{m^2y^4+y^4}=\frac{m^3y^3}{1+m^2}=\underbrace{\bigg(\frac{m^2}{1+m^2}\bigg)} \text{bounded}xy\to 0$ So there is a limit and it is $0$. Part c: The previous method do
