ON line 1 the ,-10y should be +10y. ON line 2 the, 6x-2y should remain constant as u cannot simplify it when subtracting, only when it is in a fraction.

The mistake is in the third line and it is a transfer error as the ^2 of 6x^2 and the x of the 2xy was not carried over. Also, due to this mistake, the incorrect equation has been simplified further, giving another error.

Correct Answer:

The ^2 and x must be carried down and as the equation cannot be simplified further, the answer is 6x^2 - 2xy - 15x - 10y.

It should be +10y, Not -10y.

ReplyDeleteIt should be +10y because it's -5 multiplied by -2y. Negative multiplied by negative is positive.

ReplyDeleteIt should be '+10' and not '-10' on the second line.

ReplyDeleteThe -10y in the second line should be +10y and the 6x^2 and 2xy in the second line should not have been divided by x

ReplyDelete-10y should be 10y on the scene line

ReplyDeleteIt should be +10y and not -10y on second line

ReplyDeleteIt should be +10y and not -10y on second line

ReplyDeleteLine 1 should be +10y

ReplyDeleteThere should not be that line 3 as 6x^2-2xy is not 6x-2y, making the ans wrong

If line 3 was correct, line 4 should be -9x-8y

Line 1 should be +10y

ReplyDeleteThere should not be that line 3 as 6x^2-2xy is not 6x-2y, making the ans wrong

If line 3 was correct, line 4 should be -9x-8y

It is +10 on the second line , a -5 time -2 = 10. A negative times a negative equals to a positive.

ReplyDeletethe 6x'2 was transfered wrongly and so is the 2xy

ReplyDeleteON line 1 the ,-10y should be +10y.

ReplyDeleteON line 2 the, 6x-2y should remain constant as u cannot simplify it when subtracting, only when it is in a fraction.

should remain constant at 6x^2-2xy

DeleteIt should be +10 instead of -10

ReplyDeleteIt should be +10 instead of -10

ReplyDeleteIt should be +10 and not -10

ReplyDeleteIt should be+10 and not -10 on the second line.

ReplyDeleteIt should be +10, not -10 on the second line

ReplyDeletethe -10y on the second line should be positive

ReplyDeletethe -10y on the second line should be positive

The +10 should be -10.

ReplyDelete-10y should be +10y as -5 multiply by -2y is positive which is +10y

ReplyDeleteThe third line should be 6x^2-2xy-15x+10y

The final answer is the third line

-10y should be +10y as -5 multiply by -2y is positive which is +10y

ReplyDeleteThe third line should be 6x^2-2xy-15x+10y

The final answer is the third line

It should be +10y and not -10y

ReplyDeleteIt should be +10y not -10y

ReplyDeleteOn the first line it should be +10y not -10y and on the second line 2x^2 and 2xy cannot be divided by x as it is not a fraction
