Steps to find the answer! ⬇

2^3(3)(5)➡ 120, right?
2^3 = 8 & 3(5) = 15
15(8) = 120✔

(3)(5) = 15(2) = 30
By the way if that's the case, 2 = 2, right?

✅So, option A. 2√30x would most likely be your answer to this question ✅

Good Luck!

16x 2 + 8x - 15 Mathematics?

Gala2k [10]

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)
