If (2t – 3s)(t – s) = 0, find (frac{t}{s}).
-
A.
(frac{3}{2}) or (1) -
B.
(frac{3}{2}) or (-1) -
C.
(frac{-3}{2}) or (-1) -
D.
(frac{-3}{2}) or (1)
Correct Answer: Option A
Explanation
((2t – 3s)(t – s) = 0 implies (2t – 3s) = text{0 or} (t – s) = 0)
(2t – 3s = 0 implies 2t = 3s therefore frac{t}{s} = frac{3}{2})
(t – s = 0 implies t = s therefore frac{t}{s} = 1)
(frac{t}{s} = frac{3}{2} or 1)
