2W2
2w2 - 17w + 21 is a quadratic expression which, when treated as a function of x, describes a parabola that intercepts the x-axis at the points (-1.5, 0) and (7, 0), and has a vertex at the point (4.25, -15.125). It's factors are (2w - 3), and (w - 7)

There is no equation, just an expression. And, since it is an expression, it cannot be solved so w can equal any value whatsoever.
w2 - 13w + 48You want to write the equation in the form (w+a)(w+b). However, if this particular equation could be written in this form, there would be at least one value of x where y = 0. There are no such solutions for this equation, so it cannot be factored into this form.However, you can factor it if you separate 48 into 42.25 + 5.75:w2 - 13w + 48 = (w - 6.5)2 + 5.75 = (w - 6.5)(w - 6.5) + 5.75
