Question

Can someone help me with this assignment. It would also be really helpful if you could show me how to work out the problems.

Answer 1

When adding or subtracting fractions, multiply to get the same denominator (bottom number).


`(4)/(5)*( (4)/(4)) - (1)/(4) * ((5)/(5) ) = (16)/(20) - (5)/(20) = (11)/(20)`

When multipling two fractions, just multiply straight across, factor diagonally if possible.


`(7)/(13) * (5)/(6) = (35)/(78)`

When dividing fractions, flip the second fraction over and multiply.


`(13)/(17) / (3)/(2) = (13)/(17) * (2)/(3) = (26)/(51)`

For the polynomials, you just need to combine like terms.

3x + 4y² + 7x + 6y² = (3x + 7x) + (4y² + 6y²) = 10x + 10y²

You can factor this further but I don't know if its necessary.

= 10(x + y)

Let me know if you have any questions.
