x ( x y) y ( x y) = ( x y) ( x y) = ( x y) 2 Show activity on this post Simply, Step 4 is known as factoring by grouping It is essentially an inverse of distribution, and can be proven by distributing ( a b) ( a b) to get a ( a b) b ( a b)The equation is not exact, because you'd actually need d (2xy)/dy=d (x 2 y 2 )/dx, which means that 2x=2x Letting (x 2 y 2 )=M, 2xy=N, then Mx=2x, Ny=2x So MxNy=4x Now, (MxNy)/N=4x/ (2xy)=2/y, so this is just a function of y v (y) That means that we can let u (y)=e integral of vdy u (y)=e 2ln y =1/y 2 Since the first sign is negative both signs must be negative The factors are (xy)(xy) or (xy)^2 Check by FOIL Firsts (x)(x) = x^2 Outers (x)(y) = xy Inners (y)(x) = xy Lasts (y)(y) = y^2 combine the middle terms (xy)(xy) = 2xy x^22xyy^2
