Find the difference (5a^2+4ab-+4b^2+3a^2)

Step-by-step explanation:

The differenece is obtained by subtracting the polynomial and the polynomial .

Remember that:

Then,  you need to Distribute the negative sign:

Now, you need to add the like terms. Then you get that the difference is:

1. If it is intersection then it SHOULD be included in both the sets right? Now we know that odd numbers from 1-100 but the second set are multiples of 5 from 50-150! So we mainly need to look for common numbers which are ODD and are a MULTIPLE OF 5 BETWEEN 50 - 100!! So A={51,53,57,59,6199} B={55,60,65,7095} [We stop till 100 because set A has no such element] So what is A ∩ B here? A ∩ B = {All odd numbers and multiples of 5 between 50 - 100}
