# Find the roots of the following quadratic equations by factorisation: 2x² – x +1/8 = 0

Share

2x² – x + 1/8 = 0

Solving the quadratic equation, we got

16x² – 8x + 1 = 0

⇒ 16x² – 4x – 4x + 1 = 0

⇒ 4x(4x -1) – 1(4x -1) = 0

⇒ (4x – 1) (4x -1) = 0

⇒ (4x – 1) = 0 or (4x – 1) = 0

Either x = 1/4 or x = 1/4

Hence, the roots of given quadratic equation are 1/4 and 1/4.
