Question

add the following algebraic expressions using both horizontal and vertical modes did you get the same answer with both methods (1) x2 - 2xy+3y2;5y2+3xy-6x20(2) 4a2+5b2+6ab;3ab;6a2-2b2;4b2-5ab​

Answer 1

Answer:

VERTICAL

(1)002x-2xy+6y

- 120x+3xy+10y

- 118x+1xy+16y

(2)8a+10b+6ab

00+00+3ab

12a-4b+000

00+8b-5ab

20a+14b+4ab

HORIZONTAL

(1)2x-120x-2xy+3xy+6y+10y=-118x+1xy+16y

(2)8a+12a+10b-4b+8b+6ab+3ab-5ab=20a+14b+4ab
