Factorisation (Ex. 14.4)
Find and correct the errors in the following mathematical statements:
1.
Ans. L.H.S. = R.H.S.
Hence the correct mathematical statement is
2.
Ans. L.H.S. = R.H.S.
Hence the correct mathematical statement is
3.
Ans. L.H.S. = R.H.S.
Hence the correct mathematical statement is
4.
Ans. L.H.S. = R.H.S.
Hence the correct mathematical statement is
5.
Ans. L.H.S. = R.H.S.
Hence the correct mathematical statement is
6.
Ans. L.H.S. = R.H.S.
Hence the correct mathematical statement is
7.
Ans. L.H.S. = R.H.S.
Hence the correct mathematical statement is
8.
Ans. L.H.S. = R.H.S.
Hence the correct mathematical statement is
9.
Ans.
L.H.S. = .
Hence the correct mathematical statementsis
10. Substituting in:
(a) gives
(b) gives
(c) gives
Ans. (a) L.H.S. =
Putting in given expression,
= R.H.S.
Hence gives
(b) L.H.S. =
Putting in given expression,
= R.H.S.
Hence gives
(c) L.H.S. =
Putting in given expression,
= R.H.S.
Hence gives
11.
Ans. L.H.S. =
= R.H.S.
Hence the correct statement is
12.
Ans. L.H.S. =
=
Hence the correct statement is
13.
Ans. L.H.S. =
=
= R.H.S.
Hence the correct statement is
14. (a + 4) (a + 2) = a2 + 8
Ans. L.H.S. =
= R.H.S.
Hence the correct statement is
15.
Ans. L.H.S. =
= R.H.S.
Hence the correct statement is
16.
Ans. L.H.S. = R.H.S.
Hence the correct statement is
17.
Ans. L.H.S. =
= R.H.S.
Hence the correct statement is .
18.
Ans. L.H.S. = R.H.S.
Hence the correct statement is
19.
Ans. L.H.S. = R.H.S.
Hence the correct statement is
20.
Ans. L.H.S. = R.H.S.
Hence the correct statement is
21.
Ans. L.H.S. = R.H.S.
Hence the correct statement is
