A=6i-8j B=-8+3j &C=26i+14j then find a&b such that aA+bB+C=0
a A = 6 a i - 8 a j
b B = - 8 b i + 3 b j
add i components of all 3
6 a - 8 b + 26 = 0
add j components
-8 a +3 b + 14 = 0
solve the two equations for a and b
b B = - 8 b i + 3 b j
add i components of all 3
6 a - 8 b + 26 = 0
add j components
-8 a +3 b + 14 = 0
solve the two equations for a and b
