Step-by-step explanation:
The given expression is
Then, to simplify, we need to factorize each polynomial as
x² + 7x + 10 = (x + 2)(x + 5)
x² + 4x + 4 = (x + 2)(x + 2)
x² + 3x + 2 = (x + 1)(x + 2)
x² + 6x + 5 = (x + 5)(x + 1)
So, the first step is to replace each expression with their factors
Now, we can simplify the fractions, so
Then, multiply the fractions and simplify
Answer:
Therefore, the answer is
