Question

find the roots of pure quadratic equation ax2 +c=0​

Answer 1

Step-by-step explanation:

Quadratic equation........ =___=

ax^2 +c

let e and f be roots

e + f = 0

e = -f.... (1)

e f = c/a

from (1)

(-f)f = c/a

- (f^2) = c/a

f = - √ c/a

substitute values

e +f = 0

e = √ c/a

f = -√c/a and e = √c/a is solution of given equation
