We can write 499 as 499 = 500 - 1
Because it is easy to multiply 500 and 5 compare to 499 to 5.
So product of 499 * 5 = (500 - 1)*5
= 500*5 - 1*5
= 2500 -5 = 2495
So the answer is 2495.

Answer:
(6y - 1)(6y + 1)
Step-by-step explanation:
To factorize completely, we may adopt the difference of 2 squares approach. The theory states that difference of two square is the product of the difference of the number and the sum of the numbers.
Such that
a² - b² = (a - b) (a + b)
Hence 36y² - 1
= 6²y² - 1²
= (6y)² - 1²
= (6y - 1)(6y + 1)
