ok here's an example : x^2 + 5x + 6 = 0 one way to solve is to see what 2 numbers when multiplied equal 6, and when added equal 5. well 2x3=6, and 2+3 = 5 so this equation can also be written as x^2 + 2x + 3x + 6 = 0 now, we can factor it : x(x+2) + 3(x+2) = 0 and now we have (x+2) two times. in other words, both terms have an (x+2) in common so we can factor that out aswell: (x+2) (x+3) = 0 here, since multiplying these two together results in 0; that means either one of these can equal 0. because if you multiply a number by 0, you get 0, what i'm saying is: x+2 = 0, x+3=0 so then x=2, x=3 quadratic equations always have 2 answers.
