Question

Let α → = λ - 2 a → + b → and β → = 4 λ - 2 a → + 3 b → , be two given vectors where vectors a → and b → are non-collinear. The value of λ for which vectors α → and β → are collinear, is:, - 4, - 3, 4, 3

MARKS App · Accepted Answer

∵ α → , β → are collinear then, λ - 2 4 λ - 2 = 1 3 ⇒ λ = - 4 .
