To factor the quadratic expression
, we need to find two numbers that multiply to give the product of the coefficient of
(which is 1) and the constant term (which is -28), and add up to give the coefficient of
(which is -3).The two numbers that satisfy these conditions are -7 and 4, because:
Therefore, the quadratic expression can be factored as:
So, the two binomial factors for
are
and
.
