Let's divide:-
`(2a^4 - a^3 - 2a^2 + 5a - 1) by (2a^2 + a - 3)`

Let's divide:- (m^4 - 2m^3 - 7m^2 + 8m + 12) by (m^2 - m - 6)

Let's divide:- (m^2 + 4m - 21) by (m-3)

Let's divide:- (6c^2 - 7c + 2) by (3c - 2)

Let's add : 6a^2 + 7a + 3, 9a^2 - 2a + 7, 4a^2 - 2a +9

Let's resolve into factor:- 2a^2 + 5a + 2

Let's calculate mentally :- 5a^2b - 2a^2b - 3a^2b+ 8a^2b

Let's write the value of a^3 - frac(1)(a^3) + 2 if 2a - frac(2)(a) + 1 = 0

Let's multiply :- (-3a^2) xx (4a^2b) xx (-2)

Let's Substract: (5a^2 + 2a -1) From (-9a^2 + 3a + 2)

Let's find the product by successive multiplication____ (2a^3 - 3b^3), (2a^3 + 3b^5) (2a^4 - 3a^2b^2 + b^4)
