Subtract :(a2 + b2 – 2ab) from (a2 + b2 + 2ab)

1.	Subtract :(a2 + b2 – 2ab) from (a2 + b2 + 2ab)
Answer» (a² + b² – 2ab) from (a² + b² + 2ab) The difference of two like terms is a like term whose coefficient is the difference of the numerical coefficient of the two like terms. We have, = (a² + b² + 2ab) – (a² + b² – 2ab) Change the sign of each term of the expression to be subtracted and then add. = a² + b² + 2ab – a² – b² + 2ab = (1 -1)a² + (1 – 1)b² + (2 + 2)ab = (0)a² + (0)b² + (4)ab = 4ab

Answer»

(a² + b² – 2ab) from (a² + b² + 2ab)

The difference of two like terms is a like term whose coefficient is the difference of the numerical coefficient of the two like terms.

We have,

= (a² + b² + 2ab) – (a² + b² – 2ab)

Change the sign of each term of the expression to be subtracted and then add.

= a² + b² + 2ab – a² – b² + 2ab

= (1 -1)a² + (1 – 1)b² + (2 + 2)ab

= (0)a² + (0)b² + (4)ab

= 4ab
