6. ### Curious about high school factoring

When we have a quadratic polynomial of the form: ax^2 + bx + c WHY is it factored in such a way that the newly split b term MUST MULTIPLY to make ax^2*c? For example, if we have 4x^2+4x+1 , 4x^2 +2x+2x+1 =2x(2x+1)+ 1(2x+1) =(2x+1)^2
7. ### College math courses to teach high school AP CALCULUS well?
