Step-by-step explanation:
Factoring a Non-perfect Square Trinomial. Consider (x + a) (x + b) = x² + bx + ax + ab = x² + ax + ba + ab Combine like terms. = x² + (a + b)x + ab Note the trinomial given on the right has last term ab and the coefficient of the middle term is the sum of a and b. To factor a trinomial with leading coefficient one we need only ...
