P. 3
Example 2)
3) Subtract the following polynomials.
(i) (7x + 2) from (-6x + 8)
(ii) 3xy + 5yz – 7xz + 1 from -4xy + 2yz – 2xz + 5xyz + 1
Answer : Solution:
(i) (7x + 2) from (-6x + 8)
= (-6x + 8) – (7x + 2)
= -6x + 8 – (7x + 2)
= -6x + 8 – 7x – 2
= -13x + 6
(ii) 3xy + 5yz – 7xz + 1 from -4xy + 2yz – 2xz + 5xyz + 1
= 5xz + 5xyz – 7xy – 3yz
