Please use "write" here, not "right." "write" is "right" here, if you get my drift.
"right" is wrong in this context. ;)
Example: Most of us would see immediately that 5 is a prime factor of 50.
Write 50 as 5 * 10.
10 is not prime; it can be factored into 5 and 2.
Thus, 50 written as the product of its prime factors is 5 * 5 * 2 (answer)
Step-by-step explanation:
The given quadratic equation is :

The formula to solve a quadratic equation is :

Put a = 13, b = 10 and c = 1
So,

Hence, this is the required solution.
