Step-by-step explanation:
(i) 2a2b2 + 5ab2 + 8a2b2 – 3ab2
= 2a2b2 + 8a2b2 + 5ab2 – 3ab2
= 10a2b2 + 2ab2
(ii) 4a + 3b – 2a – b
= 4a – 2a + 3b – b
= 2a + 2b
(iii) 2xy + 4yz + 5xy + 3yz – 6xy
= 2xy + 5xy – 6xy + 4yz + 3yz
= 7xy – 6xy + 7yz
= x + 7yz
(iv) ab + 15ab – 11ab – 2ab
= 16ab – 13ab = 3ab
(v) 6a2 – 3b2 + 2a2 + 5b2 – 4a2
= 6a2 + 2a2 – 4a2 + 5b2 – 3b2
= 4a2 + 2b2
(vi) 8abc + 2ab – 4abc + ab
= 8abc – 4abc + 2ab + ab
= 4abc + 3ab
(vii) 9xyz + 15yxz – 10zyx – 2zxy
= 9xyz + 15xyz – 10xyz – 2xyz
= 24xyz – 12xyz = 12xyz
(viii) 13pqr + 2p + 4q – 6pqr + 5pqr
= 13pqr + 5pqr – 6pqr + 2p + 4q
= 12pqr + 2p + 4q
(ix) 4ab + 0 – 2ba
= 4ab – 2ab + 0 = 2ab
(x) 6x2y – 2xy2 + 5x2y – xy2
= 6x2y + 5x2y – 2xy2 – xy2
= 11x2y – 3xy2
