SOLUTION: Given that the vectors, a and b are non-parallel and (2p -1)a = (q+2)b , find the value of p and of q . the answer paper shows that 2p-1 = 0 and q+2 =0 I have no idea why they

Question 1091550: Given that the vectors, a and b are non-parallel and (2p -1)a = (q+2)b , find the value of p and of q .

the answer paper shows that 2p-1 = 0 and q+2 =0
I have no idea why they are equal to zero ...
I thought it was vector a + vector b equal to zero

.

If two vectors are non-parallel and after multiplication by scalars they become equal,
it may happen in only one case:  if the scalar multipliers both are equal to 0 (ZERO).


So, 2p-1 = 0, which implies p = ,

and q+2 = 0, which implies q = -2.

Solved.
