Factor x^2+2x-63
Problem
Solution
Identify the coefficients of the quadratic expression in the form
a*x2+b*x+c wherea=1 b=2 andc=−63 Find two numbers that multiply to
c (which is−63 and add tob (which is2 .Determine the factors of
−63 that satisfy the condition:9 and−7 work because9×(−7)=−63 and9 + (-7) = 2$.Write the expression in factored form
(x+p)*(x+q) using the numbers found.
