Factor x^2-3x-54
Problem
Solution
Identify the coefficients of the quadratic expression in the form
a*x2+b*x+c wherea=1 b=−3 andc=−54 Find two numbers that multiply to the constant term
c=−54 and add to the linear coefficientb=−3 Determine the pair of numbers by testing factors of
−54 The numbers6 and−9 satisfy both conditions because6⋅(−9)=−54 and6 + (-9) = -3$.Write the factored form using these numbers as
(x+p)*(x+q)
