(4x+5)^2

Step-by-step explanation:

A special product or perfect square trinominals are of the form

(a+b)^2=a^2+2ab+b^2

Now, we will transform a little given trinominal and get the following:

16x^2+40x+25=(4x)^2+2*4x*5+5^2=(4x+5)^2

Here, in our case a=4x and b=5 and on this way we got that given trinominal is a perfect square.

3a² × 4a^5 × (4a² + b²)
12a^8(4a² + b²)
12a^8(4a²) + 12a^8(b²)
36a^10 + 12a^8b²
