Put x squared + 3x +2 into brackets first

You need to get the same denominators. So you need to multiply the second fraction by something in order to match that denominator of the first fraction.

If you factorise then it's obvious what that 'something' must be.

Have you factorized x^2+3x+2 yet?

Factorise => cross multiply => simplify

Yes
So, rewrite the first fraction using the factorization. Can you now see what you'd need to multiply the denominator of the second fraction by so both fractions have the same denominator?

Whether or not you can see what to do next, post what you've done so far. If I don't see some evidence you've actually done some maths I won't reply again.

Factories the left part first, and then times the right part by a common denominator so you can add them together.

Nope my mind is still blank
I just donβt get how did I get the same denominator I need to see the step by step method and even the numerator for the second one confused me a lot

Please post your working and we can help. Posting full solutions is against the rules.

When you factorise x^2+3x+2 you get (x+2)(x+1), to add fractions together, the denominator need to be the same, so you times top and bottom by whatever is missing from the right fractions denominator.

But that gives me 3 brackets solution

Not a good approach - the denominator should be the LCM.

You don't times both fractions only the right fractions to Make the denominator the same and make sure you times top and bottom

Can I suggest you don't start a "bidding war" of doing more and more of the question for the OP when he has shown no actual evidence of doing anything himself. He says he's done the factorization but given no evidence, he's been asked repeatedly to post working and done nothing. It's only encouraging such behaviour (and not actually helpful to teaching the OP) if people just "give in" and decide "OK, I'll post some working myself then".

Happy that you've proved me wrong by posting some working. So, as I said before, what do you need to multiply the denominator of by to get the same denominator as in ?
