(9x^2 – 12xy + 4y^2) : (– 3x + 2y) = - 3x + 2y >> 3st +(-)9x^2 - (+) 6xy 0 x^2 – 6xy + 4y^2 -(+)6xy +(-)4y^2 0 xy 0 y^2
Solution to problem is (2y -3x)Reasons: Expanding brackets : -(3x-2y)(3x-2y)---------------------(2y- 3x)Multiplying numerator and denominator by -1 gives:-(2y-3x)(3x-2y)-------------------- (2y-3x)(2y-3x) cancel out in numerator and denominator

ReplyDeleteReasons:
Expanding brackets : -
(3x-2y)(3x-2y)
---------------------
(2y- 3x)
Multiplying numerator and denominator by -1 gives:-
(2y-3x)(3x-2y)
--------------------
(2y-3x)
(2y-3x) cancel out in numerator and denominator
