First, write y in terms of x as: 1 y = 1 − 1 x. 1 y = x − 1 x. Inverting both sides: y = x x − 1 (1) Now, differentiate (1) with respect to x to obtain y ′: d y d x = d d x ( x x − 1) Apply the

Best Answer. Copy. A quadratic involving x and y is usually in the form 'y = ax2 + bx + c'. This form is y in terms of x, so we must rearrange it. y = ax2 + bx + c. y/a = x2 + bx/a + c/a.
