Factor x^2+6x-7
Problem
Solution
Identify the coefficients of the quadratic expression in the form
a*x2+b*x+c wherea=1 b=6 andc=−7 Find two numbers that multiply to
c (which is−7 and add tob (which is6 .Determine the factors by testing pairs of numbers that multiply to
−7 The pair7 and−1 satisfies both conditions because7×−1=−7 and7 + (-1) = 6$.Write the expression in factored form
(x+p)*(x+q) using the numbers found in the previous step.
