Factor 49x^2+14x+1
Problem
Solution
Identify the structure of the quadratic expression, which is in the form
a*x2+b*x+c Recognize that the first term
49*x2 is a perfect square, as(7*x)2=49*x2 Recognize that the last term
1 is a perfect square, as1=1 Check if the middle term
14*x fits the pattern2*a*b for the perfect square trinomial formulaa2+2*a*b+b2=(a+b)2 Verify the middle term by calculating
2 (7x)(1) = 14x$, which matches the given expression.Apply the perfect square trinomial formula where
a=7*x andb=1
