It should be plus 10 y at the 2nd lineNot minus 10 y at the 2nd line

Line 2: should be =10y (rightmost term)reason: negative times negative is positive

The answer is wrong

The second line, the "-10y" should be "+10y"

The first line should be +10 and not -10

Line 2 : -5 x -2y = 10yThe answer should not be negative.

2x(3x-y) - 5(3x-2y)= 6x^2 - 2xy - 15x + 10yThis should be the correct equation.

At the second line, it should be +10y and not -10y

2nd row: -10y should be +10y as - X - = +3rd row: x^2 and x is different4th row: 9x should be -9x and -2y-10y should be = -12y

NEGATIVE X NEGATIVEANS IS WRONG

The minus sign in (3x-2y) should switch to an addition sign in the second line.

The -10y from the second line should be positive

The line: 15x - 10y, should be 15x + 10y as negative 5 times negative 2y should be positive 10y.

Line 2: positive 10y

For the second line, instead of -10y it should be +10y as negative x negative = positive.

in the 3rd row, the -10y should be +10y

One of the Mathematical Symbols in the second line is wrong. The answer should be:2x(3x-y)-5(3x-2y)=6xx-2xy-15x+10y=6x-2y-15x+10y

The answer should be:At line 2: should be +10y not - 10yAt the end it should be +8y

It should be plus 10 y at the 2nd line

ReplyDeleteNot minus 10 y at the 2nd line

Line 2: should be =10y (rightmost term)

ReplyDeletereason: negative times negative is positive

The answer is wrong

ReplyDeleteThe second line, the "-10y" should be "+10y"

ReplyDeleteThe first line should be +10 and not -10

ReplyDeleteLine 2 : -5 x -2y = 10y

ReplyDeleteThe answer should not be negative.

2x(3x-y) - 5(3x-2y)

ReplyDelete= 6x^2 - 2xy - 15x + 10y

This should be the correct equation.

At the second line, it should be +10y and not -10y

ReplyDelete2nd row: -10y should be +10y as - X - = +

ReplyDelete3rd row: x^2 and x is different

4th row: 9x should be -9x and -2y-10y should be = -12y

NEGATIVE X NEGATIVE

ReplyDeleteANS IS WRONG

The minus sign in (3x-2y) should switch to an addition sign in the second line.

ReplyDeleteThe -10y from the second line should be positive

ReplyDeleteThe line: 15x - 10y, should be 15x + 10y as negative 5 times negative 2y should be positive 10y.

ReplyDeleteLine 2: positive 10y

ReplyDeleteFor the second line, instead of -10y it should be +10y as negative x negative = positive.

ReplyDeletein the 3rd row, the -10y should be +10y

ReplyDeleteOne of the Mathematical Symbols in the second line is wrong.

ReplyDeleteThe answer should be:

2x(3x-y)-5(3x-2y)

=6xx-2xy-15x+10y

=6x-2y-15x+10y

The answer should be:

ReplyDeleteAt line 2: should be +10y not - 10y

At the end it should be +8y
