Question

Simplify the following.

(i) (3x - 2y) + (3x2 – 2y) + (4y - 2x2 + x)
(ii) 3a2 - 2b2 + 2ab + 4b2 - 4a2
(iii) x²y - 3xy2 + 3xy - 4x²y - 5xy2 + 6xy
(iv) (xy + 2y) - (3xy - 4y)

Subtract the sum of the expressions.

3ab + 2ac - 3bc and 6bc -- 4ac + 2ab from
5ab- 4ac + 7bc

Subtract the sum of a2 - 3b2 + 4abc and
c2-3abc + 4a2 from the sum of
2c2 - 6abc + 2a2 and 7b2 + 5abc + 3c2.

What should be added to 3m2 - 5n2 to get
4m2 + 2n2 + 3mn?
What should be subtracted from
3x2y2 + 2xy2 - 5xy + y2 - 2x2 to get
2x2 + 3y2 – 2x2y2 – 5xy??​
