Factor x^2-2x-24
Problem
Solution
Identify the coefficients of the quadratic expression in the form
a*x2+b*x+c wherea=1 b=−2 andc=−24 Find two numbers that multiply to the constant term
c=−24 and add to the linear coefficientb=−2 Determine the pair of numbers by testing factors of
−24 the numbers4 and−6 satisfy both conditions because4⋅(−6)=−24 and4 + (-6) = -2$.Write the factored form using these two numbers as
(x+p)*(x+q)
