Is x^2 + bx + ax + ab a quadratic trinomial?
Quadratic trinomials are obtained when binomial expressions are expanded. Consider the following:
(x + a)(x + b) = x2 + bx + ax + ab
This means that quadratic trinomials of the form x2 + (a + b) x + ab when factorized will give (x + a)(x + b)
doesnt a trinomial only have 3 terms? i.e. x2 + 3x + 2
