hii mate ❤..
Answer:
x²+x/4-1/8=(x+1/2)(x-1/4)
Explanation:
Given quadratic polynomial:
x²+x/4-1/8
Splitting the middle term,weget
=x²+x/2-x/4-1/8
=x(x+1/2)-1/4(x+1/2)
=(x+1/2)(x-1/4)
Therefore,
x²-x/4-1/8=(x+1/2)(x-1/4)

Hii ☺️
you are welcome in my ans
x^2 + 1/4 - 1/8
= x^2 + 1/8
= x^2 - (-1/8)
= x^2 - sqrt (-1/8)
= (x - 1/2sqrt2 *i )(1 + 2sqrt 2 *i)
where i is iota whose value is
=>i^2 = -1
= > i = sqrt(- 1)
i called imagnary root

Hope it may helps you
