My professor insists these quadratic equations can be factored, she’s asking us to graph them as well. Maybe its just me... & Any suggestions?

To find out if a quadratic can be factored calculate the discriminant, . If is a perfect square it can be factorised. ------------------------- ------- This can be factored --------- This cannot be factored

Any quadratic "can" be factored, just not necessarily with integer coefficients. For , by the quadratic formula, its zeros are or 5/2 and -1. For we can complete the square: . the last step is factoring the "difference of two squares", (x-2)^2 and
