Ex 4.2, 1 Find the roots of the following quadratic equations by factorization: (iv) 2x2 – x + 1/8=0 2x2 – x + 1/8=0 Multiplying both sides by 8 8 × 2x2 – 8x + 8 × 1/8="8 ×" 0 16x2 – 8x + 1 = 0 We factorize using splitting the middle term method 16x2 – 4x – 4x + 1 = 0 4x (4x – 1) – 1 (4x – 1) = 0 (4x – 1) (4x – 1) = 0 4x – 1 = 0 4x = 1 x = 𝟏/𝟒 4x – 1 = 0 4x = 1 x = 𝟏/𝟒 So, x = 𝟏/𝟒 & x = 𝟏/𝟒 are the roots of equation
