find general solution to: x(dy/dx) + 2y = 4x^2

Divide through by x so: (dy/dx) +2(y/x) = 4x Now multiply through by the intergrating factor: e^(| (2/x) dx) = e^(2.ln(x)) = x^2 so you get: (x^2)(dy/dx) + 2xy = 4(x^3) Now integrate the entire equation and ...

Find Solution to x^2 + x - 2=0

Using the factorisation method. the factorised solution will look like (x+a)(x+b) = 0 by multiplying these two brackets we get the equation: x^2 + a.x+b.x + a.b = 0 so vomparing this to the equation in the q...
