If you're factoring, your answer is
(4x - 3)(4x + 5)
You'll work it out this way:
16x^2 + 8x - 15
Since there's no GCF here, you multiply the first and third terms, giving you -240. Your next step is to find two numbers that have a sum of 8 and a product of -240. These numbers are 20 and -12. Plug those in and you've got:
16x^2 + 20x - 12x - 15
From here you divide it into two binomials. These are (16x^2 + 20x) and (-12x - 15).
When you take out the greatest common factors (4x and -3), they become:
4x(4x + 5) - 3(4x + 5)
Then you group what's outside of the parentheses together (4x - 3)
And bring what's inside of the parentheses down (4x + 5).
This brings your answer to
(4x - 3)(4x + 5)
The answer for your question is -3
Well, plug in all the values.
(sqrt)3>3
False. 3 would be more than it's square root.
(sqrt)9>3
3>3
This is false. 3 is not bigger than 3. They are equal.
(sqrt)15>3
3.8729..... >3
That is true,
(sqrt)10>3
3.1622>3
This true.
-3 and 0 would not work either.
So,
"C" and "D" are correct solutions.
I hope this helps!
