Question

please answer my question if you answer in correct way hi hi ​

Answer 1

Step-by-step explanation:

1)

y-x

(m+n)/4

x²

ab/3

2).

terms=2...,(2yx and 5x)

factirisation

x(2y+5)

----------------------

terms= -7x²,4y

factorisation

-1(7x²-4y)

------------------

terms=2xy,3y²

factorisation

y(2x+3y)

-----------------

terms=3x²y,-2x²y²

factorisation

x²y(3-2y)

--------------

3).

I)... term with x= 3y²x

coefficient=3y²

ii)

term =9yx

coefficient=9y

---------------

iii)

term=4x

coefficient=4

iv)

.............

4).

I)..

12b+5b-20b-32

=17b-20b-32

=-3b-32

ii)

9z²+8z³-18z

iii

-7a-b-2ab

it is too long buddy....

so ask the question's other part again in another question........

if u r satisfied with the answers given by me

mark the answer as brainliest and thank my answers....

thank u....
