Factor x^2+11x+28
Problem
Solution
Identify the coefficients of the quadratic expression in the form
a*x2+b*x+c wherea=1 b=11 andc=28 Find two numbers that multiply to
c (28 and add tob (11 .List the factor pairs of
28 1×28 2×14 and4×7 Select the pair
4 and7 because4 + 7 = 11$.Write the expression in factored form
(x+p)*(x+q) using the identified numbers.
