The equation x2 – 1x – 90 = 0 has solutions {a, b}. what is a + b

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
