But if youre factoring a polynomial you must keep the common factor. Divide the polynomial by the factor we found thus giving us a simpler polynomial to work with. About solving equations A value c c is said to be a root of a polynomial px p x if pc 0 p c 0.
Subtract 1 from both sides.
What we have done here is factor the original expression. 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 polynomials leading coefficient and constant term in order to get a list of values that might possibly be solutions to the related polynomial equation. The graph of y 2x1 is a straight line. Here we set the target value 15.
