Answers
Step-by-step explanation:
Subtract:
Q.1
01. 18y² from 3y²
02. 6ab from –12ab
03. a + b - c from - a - b - c
04. 3ab c - a ² - b² from c² + 2a² - b² + abc
05. x ² - 3xy - 2y² from 2x² + 4xy –5y²
06. –m ² + 3mn from 3m² - 3mn + 8
07. b + c - a, c + a - b
08. 3x + 4y - 15z, 12y - 7z - 9x
09. 15a + 11b - 13c - 17, 18 - 12c - 7b - 3a
10. 3y - 5x + 3z, - x + 2y - 3z
02.
(a) Subtract 4a - 7ab + 3b + 12 from 12a - 9ab + 5b - 3
(b) Subtract 3xy + 5yz - 7zx from 5xy - 2yz - 2zx + 10xyz
(c) Subtract 4p ² q - 3pq + 5pq² - 8p + 7q - 10 from 18 - 3p - 11q + 5pq - 2pq² + 5p² q
03. From the sum of 3a - 5b + 3c and 2a + 4b - 5c, subtract 4a - b
- c + 3.
04. What should be added to x ² + xy + y² to obtain 2x² + 3xy?
05. From the sum of 2x ² + 3xy, - x² - xy - y² and xy + 2y³ , subtract
the sum of 3 x ² - y² and - x² + xy + y² .
06. Subtract the sum of 13m - 11n + 9p and - 7p + 3m - 5n from the sum of 6m - 7n - 5p, - 4m + 6p - 9n and 5m - 4n + 3p.
07. If A = 3x ² - 7x
hope it will work
