Find the two roots of each of the following (that is find the two X values that make Y = 0). This skill may be useful in assignment 11.EXAMPLE:Y = 3X² -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. Show the algebra involved.

a. Y = 3X² -3X -6.The two roots are X = ______ and X = ______.

b. Y = 140 +4X -X². The two roots are X = ______ and X = ______.
