I tried but couldnt quitw solve it :(

Answer 1

Answer: x=0.1

Explanation:

Given

The function is given by
`F(x)=x^2-0.2x+0.01`

A standard quadratic equation is given by
`ax^2+bx+c=0`

The given equation has an exponent of x as 2 which confirms it is a quadratic equation. Compare it with the standard equation

`a=1,b=0.2,c=0.01`

Therefore, the given equation is the quadratic equation.

Its solution is given by

`\Rightarrow x=(0.2\pm √((-0.2)^2-4* 1* 0.01))/(2* 1)\\\\\Rightarrow x=0.1`
