I don't want to say any things to other but the second answer of this question is wrong..he /she did the sum wrong.
Here is my answer..
Firstly,let us calculate the sum of 5x²+4xy and -3x²+2xy
= 5x²+4xy + -3x² +2xy
= 2x² + 6xy
Asked,
By how much 4x²- 7xy exceeds the sum of 5x² + 4xy and -3x² + 2xy
Means,
(4x²-7xy) - [(5x² + 4xy) + (-3x² +2xy)]-----(1)
Therefore,
We need to calculate the value of above expression..
Since we calculated the value of 5x² + 4xy + (-3x² + 2xy) which is 2x² +6xy
So, putting the value of sum in equation (1)
= (4x² -7xy) -(2x² +6xy )
= 4x² - 7xy -2x² - 6xy
= 2x² - 13xy
Thank you so much for following me..
