factor 16q^2 + 9
To factor 16q^2 + 9, we need to find two binomials whose product is equal to the given expression.
First, we can see that it is a sum of squares because 16q^2 is the square of (4q)^2 and 9 is the square of 3^2.
Using the formula for sum of squares, we have:
(4q + 3)(4q + 3)
Simplifying this expression, we get:
(4q + 3)^2
Therefore, 16q^2 + 9 can be factored as (4q + 3)(4q + 3) or (4q + 3)^2.
