Answer:
The equivalent expression is: (6x + 5)*(6x - 5)
Step-by-step explanation:
This expression is called the difference of two squares.
It has the following format: [tex]a^{2} - b^{2}[/tex]
It is factored as: [tex]a^{2} - b^{2} = (a-b)*(a+b)[/tex]
In this question:
[tex]a^{2} - b^{2} = 36x^{2} - 25[/tex]
So
[tex]a^{2} = 36x^{2}[/tex], then [tex]a = \sqrt{36x^{2}} = 6x[/tex]
[tex]b^{2} = 25[/tex], then [tex]b = \sqrt{25} = 5[/tex]
So
The equivalent expression is: (6x + 5)*(6x - 5)
Answer:
The answer is D: (6x)2 − (5)2
