Assignment Help Basic Statistics
Reference no: EM132479728

Find the two roots of each of the following quadratic functions (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 -14X -24. The two factors are X = ______ and X = ______.

b. Y = 8X2 +14X -15. The two factors are X = ______ and X = ______.
