Let `A=3x^(2)-7xy+6 and B= 7xy-5x^(2)+15`
Find.
(I) `A+B " " (II) 2A+B`

Let A=3x^(2)-7xy+6 and B=7xy-5x^(2)+15 Find. (I) A-B " " (II) 3A-2B

A={x|3x^2-7x-6=0},B={x|6x^2-5x-6=0} . Find A nn B

Multiply : 3x^(2) y - 7xy^(2) +2xy" by " 4xy

Let A = { 2,3,5,7,9 } and B = { 2,3,4,5,6} Find A - B and B - A

A=2x+3xy+7x^(2),B=3x-2y-5x^(2) and C=2xy-6x^(2)-3x . Find the value of A+B+C.

If A = 7x^(2) + 5xy - 9y^(2), B = - 4x^(2) + xy + 5y^(2) and C = 4y^(2) - 3x^(2) - 6xy then show that A + B + C = 0

simplify: (i) 2p^(3) - 3p^(2) + 4p - 5- 6p^(3) + 2p^(2) - 8p - 2 + 6p + 8 (ii) 2x^(2) - xy + 6x - 4y + 5xy - 4x + 6x^(2) + 3y (iii) x^(4) - 6x^(3) + 2x - 7 + 7x^(3) - x + 5x^(2) + 2 - x^(4)

Subtract: (i) 5a + 7b - 2c from 3a - 7b + 4c (ii) a - 2b - 3c from -2a + 5b - 4c (iii) 5x^(2) - 3xy + y^(2) from 7x^(2) - 2xy - 4y^(2) (iv) 6x^(3) - 7x^(2) + 5x - 3 from 4 - 5x + 6x^(2) - 8x^(3) (v) x^(3) + 2x^(2) y + 6xy^(2) - y^(3) from y^(3) - 3xy^(2) - 4x^(2) (vi) -11 x^(2) y^(2) + 7xy - 6 from 9x^(2) y^(2) - 6xy + 9 (vii) -2a + b + 6d from 5a - 2b - 3c

If A = 3y^(2) + 4x - 5x^(2), B = x^(2) - 3y^(2) and C = 2x^(2) - 7xy then find A - B

Add: 4x^(2) - 7xy + 4y^(2) - 3, 5 + 6y^(2) - 8xy + x^(2) and 6 - 2xy + 2x^(2) - 5y^(2)
