Verified Answer
What are the sum and product of the roots of the equation x2 - 3x + 4 ...
Given: 
Quadratic equation =  x
2
 - 3x + 4 = 0
Formula used:
Quadratic equation: ax
+ bx + c = 0
The sum of the roots = α + β = 
Product of the roots =
α × β = 
 
Calculation:
The sum of the roots =
α + β
=
 = 3
Product of the roots 
α × β
 = 
41
 = 4
∴ 3 and 4 are the sum and product of the roots of the equation x
2
 - 3x + 4 = 0.
