Question

subtract the sum of 4a +2b+ c, 2a- 2b +c, +c, -a +2c and 4a +2b -5 from 5a -4b +2c​

Answer 1

Step-by-step explanation:

(i). (4a + 2b + c) - (5a - 4b + 2c)

= 4a + 2b + c - 5a + 4b - 2c

= - a + 6b - c

(ii). (2a - 2b + c) - (5a - 4b + 2c)

= 2a - 2b + c - 5a + 4b - 2c

= -3a + 2b - c

(iii). (- a + 2c) - (5a - 4b + 2c)

= - a + 2c - 5a + 4b - 2c

= - 6a + 4b

(iv). (4a + 2b - 5) - (5a - 4b + 2c)

= 4a + 2b - 5 - 5a + 4b - 2c

= - a + 6b - 2c - 5
