Question

Subtract the following polynomials.
(i) (7x + 2) from (-6x + 8)
(ii) 3xy + 5yz – 7xz + 1 from -4xy + 2yz – 2xz + 5xyz + 1
(iii) 2x2y2– 3xy + 4 from 4x2y2 + 10xy

​

Answer 1

Explanation:

(i) = (-6x+8)-(7x+2)

= -6x+8-7x-2

= -6x-7x+8-2

= -13x+6

Answer 2

Answer:

i.13x-6

ii.7xy+3yz-5xz-5xyz

iii.-2x-13xy+
