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
