Find the equation if the roots are: x = -3/4 and x = 8
If the roots are x = -3/4 an x = 8, then the factors are:
x%2B3%2F4+=+0 and x-8+=+0 Multiply these factors to find the equation.
%28x%2B3%2F4%29%28x-8%29+=+x%5E2-8x%2B%283%2F4%29x-6 Combine like-terms:
x%5E2-%2829%2F4%29x-6 Now multiply through by 4 to clear the fraction.
4x%5E2-29x-24
