Question

calcule a adição algébrica de polinômios

a) (2x+3y) + ( 5x+y) =

b) (9m+ -5) - (3m+ 2)=

c) 8y- ( 2y-5) + ( 6y+ 13) =

Answer 1

a) (2x+3y) + (5x+y)= 2x + 3y + 5x + y= 7x + 4y

b) (9m- 5) - (3m+2)= 9m - 5 - 3m - 2 = 6m -7

c) 8y - (2y-5) + (6y+13) = 8y - 2y + 5 +6y + 13 = 12y + 18

Answer 2

a) (2x+3y) + ( 5x+y) =

2x + 3y + 5x + y

7x + 4y

b) (9m+ -5) - (3m+ 2)=

9m - 5 - 3m - 2

6m - 7

c) 8y- ( 2y-5) + ( 6y+ 13) =

8y - 2y + 5 + 6y + 13

6y + 6y + 18

12y + 18
