Factoring Polynomials - Math
Example. The discriminant of 4x 22x+2 equals (2) 4(4)(2) = 432 = 228, a negative number. Therefore, 4x 2x +2hasnoroots, anditis completely factored as 4(x2 1 2x+ 1 2). 2Roots.If the quadratic polynomial ax2 + bx + c has 2 roots, we can name them ↵1 and ↵2. Roots give linear factors, so we know that (x ↵1) 159

You should study scatter plots of each pair of independent variables, using a different color for each group. Look carefully for curvilinear patterns and for outliers. The occurrence of a curvilinear relationship will reduce the power and the discriminating ability
