A) \[-195\]
B) 2535
C) \[-2535\]
D) 7605
Correct Answer: C
Solution :
We have, \[4xy(x-y)-6{{x}^{2}}(y-{{y}^{2}})\] \[-3{{y}^{2}}(2{{x}^{2}}-x)+2xy(x-y)\] \[=4{{x}^{2}}y-4x{{y}^{2}}-6{{x}^{2}}y+6{{x}^{2}}{{y}^{2}}-6{{x}^{2}}{{y}^{2}}+3x{{y}^{2}}\]\[+2{{x}^{2}}y-2x{{y}^{2}}\] \[=(4{{x}^{2}}y-6{{x}^{2}}y+2{{x}^{2}}y)+(-4x{{y}^{2}}+3x{{y}^{2}}-2x{{y}^{2}})\]\[+(6{{x}^{2}}{{y}^{2}}-6{{x}^{2}}{{y}^{2}})\] \[=0-3x{{y}^{2}}+0=-3(5)\times {{(13)}^{2}}\] \[=-3\times 5\times 169=-2535\]You need to login to perform this action.
