Find the two roots of each of the following functions (that is find the two X values that make Y = 0).
EXAMPLE: Y = 3X^2 -11X +6 is the product of (3X -2)(X -3). If you let Y = 3X-2 then X = 2/3 will make Y = 0. If you let Y = X-3 then X = 3 will make Y = 0. Thus both X = 2/3 and X = 3 are roots.
A. Y = 4X^2 +4X -8. The two roots are X = ______ and X = ______.
B. Y = 5X^2 +X -6. The two roots are X = ______ and X = ______.
We have given
We have to find two roots of the given functions
For part a
Let y = 4x-4 then x = 1 will make y = 0
Let y = x+2 then x=-2 will make y = 0
