If `( 2x - 5 )/( x - 3 )^2 = a /( x - 3 ) + b/( x - 3 )^2` , then find a + b =
1 ) 1
2 ) 2
3 ) 3

If A = 3x^(2) + 2x - 7 and B = 7x^(3) - 3x + 4 , then find : A - B

If A = 3x^(2) + 2x - 7 and B = 7x^(3) - 3x + 4 , then find : A + B

The HCF of the polynomials (2x - 1) (5x^(2) -ax + 3) and (x -3) (2x^(2) + x +b) " is " (2x -1) (x -3) Then the values of a and b respectively are _____
