Answer 3

math celebrity explains:

Factor 4x2 + 16x

Evaluating the expression you entered, we can factor out a constant of 4
Factor out 4 from 4x2
Our new constant becomes 4 ÷ 4 = 1
Our new term becomes x2

Factor out 4 from 16x
Our new constant becomes 16 ÷ 4 = 4
Our new term becomes 4x

Our factored expression is as follows:
4(4x + x2)
