16x^2+?x+36 perfect square trinomial

Hunter-Best [27]

Answer:

16x² +48x +36

Step-by-step explanation:

A perfect square trinomial is of the form ...

(a +b)² = a² +2ab +b²

We want to match this form.

<h3>comparing terms</h3>

Comparing the known terms, we see ...

16x² = a² ⇒ a = 4x

36 = b² ⇒ b = 6

<h3>filling in the missing term</h3>

The missing term is the linear term:

2ab = 2(4x)(6) = 48x

? = 48

Can you please help me

Answer:

Step-by-step explanation:

Hi there!

To answer this, we must set it up as

$3x(2x^4-12x^2+7)$

Now we just use the distributive property to solve.

this becomes $6x^5-36x^3+21x$

I hope this helps!
