Decide math equation

Summary We can directly solve polynomials of Degree 1 (linear) and 2 (quadratic) For Degree 3 and up, graphs can be helpful It is also helpful to: Know how far left or right the roots may be Know how many roots (the same as its degree)

The first step in finding the solutions of (that is, the x -intercepts of, plus any complex -valued roots of) a given polynomial function is to apply the Rational Roots Test to the polynomial's

Math is often viewed as a difficult and dry subject, but it can be made much simpler by breaking it down into smaller, more manageable pieces.

First, we need to notice that the polynomial can be written as the difference of two perfect squares. 4x2 − y2 = (2x)2 −y2 Now we can apply above formula with a = 2x and b = y (2x)2 −y2
