For function f (x) = 4x² - 36x + 81 , in relation to the roots, it is correct to say that it has two equal roots.

a second degree function is of the form f (x) = ax² + bx + c, with ≠ 0.

to know A amount of roots of function f, we must remember that:

Remember that delta is defined by:

Let's determine the function of the F function.

na Function f (x) = 4x² - 36x + 81 , we have that coefficient values ​​ are a = 4, b = -36 and c = 81.

Calculating Delta value , we get:

Δ = (-36) ² - 4.4.81

Δ = 1296 - 1296

Δ = 0.

Following what has been said, we can say that a F Function has two equal real root

Answer:

f(x) = 4x² - 36x + 81 = (2x - 9)²

The root of f(x) is 4.5, with multiplicity 2.
