Forming a Quadratic Polynomial with Zeroes 2α and 2β
Finding the Zeroes of the Given Polynomial
To find the zeroes of the polynomial 4x² + 4x + 1, we can use the quadratic formula:
x = (-b ± √(b² - 4ac)) / 2a
Plugging in the values of a, b, and c from our polynomial, we get:
x = (-4 ± √(16 - 16)) / 8
Simplifying, we get:
x = (-4 ± 1) / 8
Which gives us the two zeroes: α = -1/2 and β = -1/2.
Finding the Zeroes of the Desired Quadratic Polynomial
We want to find a quadratic polynomial with zeroes 2α and 2β. To do this, we can use the fact that if a polynomial has zeroes α and β, then it can be written as:
P(x) = (x - α)(x - β)
Thus, a quadratic polynomial with zeroes 2α and 2β can be written as:
Q(x) = (x - 2α)(x - 2β)
Plugging in the Values of α and β
We already know the values of α and β from the given polynomial. Plugging these values into the expression for Q(x), we get:
Q(x) = (x - 2(-1/2))(x - 2(-1/2))
Simplifying, we get:
Q(x) = (x + 1)(x + 1)
Which is the desired quadratic polynomial.
