1.	If →a,→b,→c are non-zero vectors such that \|→a\|=\|→b\| and →a⋅(2→a+→b−→c)=→b⋅(→a+2→b+→c), then which of the following is/are true ?
Answer» If $\to a, \to b, \to c$ are non-zero vectors such that $\| \to a \| = \| \to b \|$ and $\to a \cdot (2 \to a + \to b - \to c) = \to b \cdot (\to a + 2 \to b + \to c),$ then which of the following is/are true ?
