Question

The roots of the quadratic equation x²+16=0 are​

Answer 1

Step-by-step explanation:

it can be written in the form of x²+0.x+16=0

by using quadratic formula

= (-b) +-√b²-4ac/2a

here a= 1,b=0 and c = 16

= -(0)+-√0²-4×1×16/2

= 0+-√-64/2

0+-(8)/2

taking + side we get 0+8/2 and taking -ve side 0-8/2

= 4,-4
