Factor x^2+10x-75
Problem
Solution
Identify the coefficients of the quadratic expression in the form
a*x2+b*x+c wherea=1 b=10 andc=−75 Find two numbers that multiply to
c (which is−75 and add tob (which is10 .Determine the pair of numbers by testing factors of
−75 the numbers15 and−5 satisfy both conditions because15⋅(−5)=−75 and15 + (-5) = 10$.Write the factored form using these two numbers as
(x+p)*(x+q)
