Answer:
If it is a quadratic equation then it's zeroes are alpha and beta. Sum of zeroes is -b/a. So alpha plus beta is -b divided by a.
Step-by-step explanation:
The formula used for making an equation when you know the zeroes is;
- k(x² - (sum of zeroes)x + (product of zeroes)
- k(x² - (α+β)x + (αβ))
k here,is a constant; for better clarification follow this example;
Say
- (α+β) = 1
- (αβ) = 2
According to the formula the equation must be;
- k(x² - (α+β)x + (αβ))
- k(x² - (1)x + (2))
- k(x² - 1x + 2)
Now, the k can be replaced with any variable, i.e, 3,4,5/6,7 etc anything. Hope it was clear.
