Question

add the following algebraic expression using both horizontal and vertical methods.did you get the same answer with both methods x2-2xy+3y2;5y2+3xy-6x2

Answer 1

yes it same sister............

Answer 2

Yes, the answer will be same using both the methods.

•Given equations

2XY +3Y2 ; 5Y2 + 3XY - 6×2

•Adding by horizontal method

2XY + 3Y2 ; 5Y2 + 3XY - 6x2

Arranging similar terms together we get

( 2XY + 3XY ) + (3Y2 + 5Y2) - 6x2

5XY + 8Y2 - 12

• Adding by Vertical method

2XY + 3Y2 ; 5Y2 + 3XY - 6x 2

Arranging similar terms together we get

2XY + 3Y2

3XY + 5Y2 - (6x2)

-------------------------------

5XY + 8Y2 - 12

Hence it is proved.
