Question

i request u to tell me the answer of 10th question pls help i will thank ur 20 answers and mark u as brainlist and also follow u

Answer 1

Answer:

(i) 5x^2 - 6x - 2 = 0

Discriminant (D) = √(b^2-4ac)

D = √(36 - 4(5)(-2))

D = √76.

Since, Discriminant is positive so, the roots are real and distinct.

(ii) x^2 - 3√3x + 12 = 0

D = √(27 - 48)

D = √-21.

Which is imagenary so, roots of this equation is imagenary .

Thanks!
