Question 70

In the following question, state whether the statement is True (T) or False (F):

$x^{2} + (a + b) x + a b = (a + b) (x + a b)$

In the following, state whether A = B or not:

(i) A = {a, b, c, d}; B = {d, c, b, a}

(ii) A = {4, 8, 12, 16}; B = {8, 4, 16, 18}

(iii) A = {2, 4, 6, 8, 10}; B = {x: x is positive even integer and x ≤ 10}

(iv) A = {x: x is a multiple of 10}; B = {10, 15, 20, 25, 30 ...}

1 \in \{1, 2, 3\}

a \subset {b, c, a}

\{a\} \in \{a, b, c\}

\{a, b\} = \{a, a, b, b, a\}

In each case, find whether the trinomial is a perfect square or not :

$(i) x^{2} + 14 x + 49$ $(i i) a^{2} - 10 a + 25$

$(i i i) 4 x^{2} + 4 x + 1$ $(i v) 9 b^{2} + 12 b + 16$

$(v) 16 x^{2} - 16 x y + y^{2}$ $(v i) x^{2} - 4 x + 16$

A = B

A = {a, b, c, d} B = {d, c, b, a}

A = {4, 8, 12, 16} B = {8, 4, 16, 18}

A = {2, 4, 6, 8, 10} B = {x : x is a positive even integer and x \leq 10}

A = {x : x is a multiple of 10}, B = {10, 15, 20, 25, 30, . . .}
