Answer:
(3n - 8)(2n + 5)
Step-by-step explanation:
6n² - n - 40
Consider the factors of the product of the coefficient of the n² term and the constant term which sum to give the coefficient of the n- term
product = 6 × - 40 = - 240 and sum = - 1
The factors are - 16 and + 15
Use these factors to split the n- term
6n² - 16n + 15n - 40 ( factor the first/second and third/fourth terms )
2n(3n - 8) + 5(3n - 8) ← factor out (3n - 8) from each term
(3n - 8)(2n + 5)
Then
6n² - n - 40 = (3n - 8)(2n + 5)
Use the Pythagorean theorem:
The ladder will reach approximately 14.14 feet (exactly 10√2 feet) up on the building.
I think it’s 1/2 divided by 2
You need to be clearer on what the "roots" are, I haven't learned that term ever, but I think I know what you mean...
