Answer:
Step-by-step explanation:
Alright, let get started.
The given equation is :
This is a quadratic equation.
The standard form of a quadratic equation is :
Comparing the given equation with standard one, the values of A ,B and C are :
A is 1
B is -1
C is -90
Since a and b are the roots of the equation, so the formula for sum of roots a+b will be =
a+b=
hence a+b will be 1 : Answer
