U do not understand ur language I am sorry I can't help
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)

Answer:
The answer to your question is letter B
Step-by-step explanation:
Process
1.- Write the function
f(x) = - 2x² + 2x - 3
Find f(5)
2.- Substitute x for 5
f(5) = -2(5)⁵ + 2(5) - 3
3.- Simplify
f(5) = -2(25) + 10 - 3
f(5) = -50 + 7
f(5) = -43
