Factor x^2-3x-28
Problem
Solution
Identify the coefficients of the quadratic expression in the form
a*x2+b*x+c wherea=1 b=−3 andc=−28 Find two numbers that multiply to the constant term
c=−28 and add to the linear coefficientb=−3 Determine the factors of
−28 that satisfy the condition:4 and−7 work because4⋅(−7)=−28 and4 + (-7) = -3$.Write the expression in factored form
(x+p)*(x+q) using the numbers found.
