Factor x^2-14x+45
Problem
Solution
Identify the coefficients of the quadratic expression in the form
a*x2+b*x+c wherea=1 b=−14 andc=45 Find two numbers that multiply to the constant term
c=45 and add up to the linear coefficientb=−14 Determine the factors of
45 that satisfy the condition. Since the product is positive and the sum is negative, both numbers must be negative. The numbers−5 and−9 work because(−5)×(−9)=45 and(−5)+(−9)=−14 Rewrite the expression in factored form
(x+p)*(x+q) using the numbers found in the previous step.
