Answer 2

Quadratic equation -

4x² - 0 • X +1

Quadratic formula -

-b (+,-) √b² - 4ac/2a

According to question -

Given -

a = 4

b = 0

c = 1

Putting these values in the formula,

X = -0 (+,-)√(0)² - 4 × 4 × 1/2 ×4

X = -0 (+,-)√0 - 16 /8

X = (+,-)√-16/8

X = (+,-) √-2

Now,

X = √-2

and

X = - √-2

here is your answer
