Factor 10x^2+17x+3
Problem
Solution
Identify the coefficients of the quadratic expression
a*x2+b*x+c wherea=10 b=17 andc=3 Find two numbers that multiply to
a*c=10⋅3=30 and add tob=17 Determine the pair of numbers, which are
15 and2 since15⋅2=30 and15 + 2 = 17$.Rewrite the middle term
17*x using the two numbers found:10*x2+15*x+2*x+3 Factor by grouping the first two terms and the last two terms:
5*x*(2*x+3)+1*(2*x+3) Factor out the common binomial
(2*x+3) to obtain the final factored form.
