Factor x^2-12x+35
Problem
Solution
Identify the coefficients of the quadratic expression in the form
a*x2+b*x+c wherea=1 b=−12 andc=35 Find two numbers that multiply to equal
c (35 and add to equalb (−12 .Determine the factors of
35 that satisfy the condition. Since the product is positive and the sum is negative, both numbers must be negative. The pairs are(−1,−35) and(−5,−7) Select the pair
(−5,−7) because−5+(−7)=−12 Write the factored form using these two numbers as
(x+p)*(x+q)
