Factor x^2-x-110
Problem
Solution
Identify the coefficients of the quadratic expression in the form
a*x2+b*x+c wherea=1 b=−1 andc=−110 Find two integers that multiply to
c (which is−110 and add tob (which is−1 .Determine the factors of
−110 by testing pairs:10×−11=−110 and10 + (-11) = -1$.Write the expression in factored form
(x+p)*(x+q) using the integers found.
