Answer:
After finding like terms and solving, we get 
Step-by-step explanation:
We need to find like terms and simplify the expression 
Like terms: The terms who have same variable and exponent are called like terms.
So, Combining like terms and solving:

So, after finding like terms and solving, we get 
<u><em>Note: In the question given we have - and + sign with the term 5x</em></u> i.e 4- 2x + x^2 -+ 5x + 12 + 2x^2
I have solved using +5x, but if the term is -5x then the solution will be:

So, the answer will be: 
Answer:
Step 1: Make sure the bottom numbers (the denominators) are the same
Step 2: Add the top numbers (the numerators), put that answer over the denominator
Step 3: Simplify the fraction (if needed)
Step-by-step explanation:
It would be: 32/48 = 16/24 = 8/12 = 4/6 = 2/3
[ Just try to divide numerator & denominator by 2, until they reach at the position, when they can't reduce anymore ]
In short, Your Answer would be 2/3
Hope this helps!
