What are the zeroes of f(x)=x+5-2x^2

The zeros of the function are x = -1.35 and x = 1.85

Step-by-step explanation:

The given function is f(x) = x + 5 - 2x²

⇒ f(x) = - 2x² + x + 5

To find the zeroes of the function we are assuming f(x) = 0 and solve the equations.

Hence, - 2x² + x + 5 = 0

Applying Sridhar Acharya's formula

and

⇒ and  

⇒ x = -1.35 and x = 1.85  

Therefore, the zeros of the function are x = -1.35 and x = 1.85 (Answer)
