Question

The integral ∫ d x x + 1 3 4 x - 2 5 4 , is equal to, 4 x - 2 x + 1 1 4 + c, - 4 3 x + 1 x - 2 1 4 + c, 4 x + 1 x - 2 1 4 + c, - 4 3 x - 2 x + 1 1 4 + c

MARKS App · Accepted Answer

∫ d x x + 1 3 4 x - 2 5 4 = ∫ d x x + 1 2 x - 2 x + 1 5 4 Put, x - 2 x + 1 = t ⇒ 3 x + 1 2 d x = d t ∴ I = - 4 3 1 t 1 4 + c = - 4 3 x + 1 x - 2 1 4 + c , c being the constant of integration.
