Question 56 (c)
Simplify the following by combining the like terms and then write whether the expression is a monomial, a binomial or a trinomial.
p3q2r+pq2r3+3p2qr2−9p2qr2
Simplify : ( 3p+ pq) - ( p- q)
(i) 21b − 32 + 7b − 20b
(ii) − z2 + 13z2 − 5z + 7z3 − 15z
(iii) p − (p − q) − q − (q − p)
(iv) 3a − 2b − ab − (a − b + ab) + 3ab + b − a
(v) 5x2y − 5x2 + 3y x2 − 3y2 + x2 − y2 + 8xy2 −3y2
(vi) (3 y2 + 5y − 4) − (8y − y2 − 4)
