**Finding the Value of Alpha^2 and Beta^2**
To find the value of alpha^2 and beta^2, we need to first determine the values of alpha and beta. These values can be found by using the quadratic formula, which is given by:
x = (-b ± √(b^2 - 4ac)) / 2a
where a, b, and c are the coefficients of the quadratic equation ax^2 + bx + c = 0.
**Step 1: Finding the Values of Alpha and Beta**
Given that alpha and beta are the zeroes of the quadratic polynomial ax^2 + bx + c, we can set the equation equal to zero:
ax^2 + bx + c = 0
Using the quadratic formula, we can substitute the values of a, b, and c into the formula to find the values of alpha and beta:
alpha = (-b + √(b^2 - 4ac)) / 2a
beta = (-b - √(b^2 - 4ac)) / 2a
**Step 2: Finding the Values of Alpha^2 and Beta^2**
Now that we have the values of alpha and beta, we can find their squares:
alpha^2 = (-b + √(b^2 - 4ac))^2 / (2a)^2
beta^2 = (-b - √(b^2 - 4ac))^2 / (2a)^2
Simplifying these expressions further, we get:
alpha^2 = (b^2 - 2ab + (b^2 - 4ac)) / (4a^2)
beta^2 = (b^2 + 2ab + (b^2 - 4ac)) / (4a^2)
alpha^2 = (2b^2 - 4ab + 4ac) / (4a^2)
beta^2 = (2b^2 + 4ab + 4ac) / (4a^2)
Simplifying these expressions even further, we get:
alpha^2 = (b^2 - 2ab + 4ac) / (2a^2)
beta^2 = (b^2 + 2ab + 4ac) / (2a^2)
Therefore, the values of alpha^2 and beta^2 are given by the expressions:
alpha^2 = (b^2 - 2ab + 4ac) / (2a^2)
beta^2 = (b^2 + 2ab + 4ac) / (2a^2)
These expressions can be used to calculate the values of alpha^2 and beta^2, given the coefficients a, b, and c of the quadratic equation.
