Write `( p + 2q + r) ^(2)` in expanded from.

Write the following cubes in the expanded form (2p-5)^3

Write G.P. If a = 256, r = (-1)/2 .

If p, q, r are in A.P the p^(2) (q + r), q^(2) (r + p), r^(2) (p+q) are in

Expand R.U.B.P.

Write 3 like terms for 7p^(2)q^(2)

Find the vector joining the points P(2,3,0) and Q(-1,-2,-4) directed from P to Q.

If the inverse of implication p rarr q is defined as ~p rarr ~q , then the inverse of the proposition (p ^^ ~q) rarr r is not equivalent to : I : ~r rarr p vv q II : ~p vv ~q rarr ~r III : r rarr p ^^ ~q The true statements in the above are :

If x^(2) - px + q = 0 (p,q in R and p ne 0, q ne 0) has distinct real roots. Then…

If p^(th), q^(th), r^(th) and s^(th) terms of an A.P. are in G.P, then show that (p – q), (q – r), (r – s) are also in G.P.
