Solution

The correct option is B
(7, 9)

When reflected through the origin, both the coordinates will change their sign i.e. (x, y) becomes (-x, -y) or (-x, -y) becomes (x, y) depending upon the sign. So, if we have, the coordinates (-7, -9) its reflection through the origin gives us (7, 9) as a resultant point.

If the coefficient of $x^{2}$ and $x^{3}$ in the expansion of $(3 + a x)^{9}$ are the same, then the value of a is

$(7 a^{2} - 63 b^{2}) = ? (a) (7 a - 9 b) (9 a + 7 b) (b) (7 a - 9 b) (7 a + 9 b) (c) 9 (a - 3 b) (a + 3 b) (d) 7 (a - 3 b) (a + 3 b)$

Q. Tick (✓) the correct answer:
(7a² − 63b²) = ?
(a) (7a − 9b)(9a + 7b)
(b) (7a − 9b)(7a + 9b)
