A curve has the equation x^2+2y^2=3x, by differentiating implicitly find dy/dy in terms of x and y.

We shall differentiate each term in the equation with respect to x. dy/dx (x 2 ) = 2x dy/dx (2y 2 ) = 4y dy/dx dy/dx (3x) = 3 So we now have the equation 2x + 4y dy/dx =3 We now have to rearrange to get in t...

Expand (2x-4)(x+3)

We are going to use the F.O.I.L Method for this expansion, FIRST 2x*x = 2x 2 OUTSIDE 2x*3 = 6x INSIDE -4x*x = -4x LAST -4*3 = -12 Now to add up all the terms we have found 2x 2 +6x-4x+12 = 2x 2 +2x+12
