Question

Add the following:
(i) 2a,4b,-3a
(ii) 6xy,-2xy,14yz
(iii) 3x,-5y,-2x,6y
(iv)8x2,-11y2,6y2,-3x2
(v) 9abc,-6bc,abc,-bc
(vi)7x2y,8xy2,-4x2y,-5xy​

Answer 1

Answer:

here are your answers

1. 2a+4b+(-3a)=2a+4b-3a= -a+4b
2. 6xy-2xy+14yz= 4xy+14yz
3. 3x-5y-2x+6y=3x - 2x - 5y +6y=X + Y
4. 8 x^2-11y^2+6y^2-3x^2= 5x^2-5y^2
5. 9 abc -6 b C + abc - bc=10abc-7bc
6. 7x^2y+8xy^2-4x^2y-5xy=3x^2y+8 x y^2-5xy

Answer 2

Answer:

1. 2a + 4b + (- 3a) = 2a + 4b - 3a = - a + 4b

2. 6xy - 2xy + 14yz = 4xy + 14yz

3. 3x - 5y - 2x + 6y = 3x - 2x - 5y + 6y = x + y

6. 7x^ ^ 2y+8xy^ ^ 2-4x^ ^ 2y - 5xy =3x^ ^ 2y+8* y^ ^ 2-5xy

5. 9 abc -6 b C + abc - bc=10abc-7bc

4. 8 x^ ^ 2-11y^ ^ 2+6y^ ^ 2-3x^ ^ 2=5x^ ^ 2-5y^ ^ 2
