Factor w^2+18w+77
Problem
Solution
Identify the coefficients of the quadratic expression in the form
a*w2+b*w+c wherea=1 b=18 andc=77 Find two numbers that multiply to
c (77 and add up tob (18 .Test factors of
77 the pairs are1×77 and7×11 Select the pair
7 and11 because7 + 11 = 18$.Write the factored form as
(w+p)*(w+q) using the identified numbers.
