To graph a polynomial, you'll want to know as many key features as possible, including x and y intercepts and end behavior. To find the x-intercepts, set each factor equal to zero and solve for x. The real solutions will show up as x-intercepts on the graph. You may need a decimal approximation in some cases like the example here, where the zero is irrational. To find the y-intercept, as always, let x = 0. Consider the end behavior to sketch the direction in which your y-values will go as x gets very large or very small.
