Sum of the zeroes = 21/8

Product of the zeroes = 5/16

**P(x) = x**^{2} – (sum of the zeroes) + (product of the zeroes)

Then, P(x)= x^{2} – 21x/8 + 5/16

P(x)= 16x^{2} – 42x + 5

**Using splitting the middle term method,**

16x^{2} – 42x + 5 = 0

16x^{2} – (2x + 40x) + 5 = 0

16x^{2} – 2x – 40x + 5 = 0

2x (8x – 1) – 5(8x – 1) = 0

(8x – 1)(2x – 5) = 0

⇒ x = 1/8, 5/2
