Find two numbers whose sum is 15 and the product is 36

ycow [4]

The two numbers are 3 and 12.

I got these numbers by factoring 36.

1 * 36 sum : 37
2 * 18 sum : 20
3 * 12 sum : 15

It is easier to find the factor of a number and solve for the sum. Than to find the addends of a number and solve for the product.

There are 9 factors of 36 while 14 addends of 15.

The general solution of 2 y ln(x)y' = (y^2 + 4)/x is

Sav [38]

Replace $y'$ with $\dfrac{\mathrm dy}{\mathrm dx}$ to see that this ODE is separable:

$2y\ln x\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{y^2+4}x\implies\dfrac{2y}{y^2+4}\,\mathrm dy=\dfrac{\mathrm dx}{x\ln x}$

Integrate both sides; on the left, set $u=y^2+4$ so that $\mathrm du=2y\,\mathrm dy$ ; on the right, set $v=\ln x$ so that $\mathrm dv=\dfrac{\mathrm dx}x$ . Then
