Question

4x^2-(2/3)x-(1/16)=0

Answer 1

$4x^2 - \frac{2x}{3} - \frac{1}{16} = 0$
On simplification
$192x^2 - 32x - 3 = 0$
$192x^2 - 48x +12x - 3 = 0$
$192x^2 - 48x +<span>12x - 3 = 0$
48x(4x - 1) + 3(4x - 1) = 0
(4x - 1)(48x + 3) = 0

x = 1/4   or x = -3/48 = -1/16

Answer 2

4x²-2x/3-1/16=0
on simplifying
       192x²-32x-3=0
⇒    192x²- 24x-8x-3=0
⇒    24x(8x-1)-(8x-1)-4=0
⇒  (8x-1)(24x-1)=4
