Answer:
Solution -
We know that for a quadratic equation of the form ,
ax² + bx + c
Sum of roots = ( - b / a )
Where ,
a is the leading coefficient
b is the trailing coefficient .
So, this can be also written as :
Sum of roots of a quadratic equation -
=> - [ Leading Coefficient / Trailing Coefficient ]
Here , the following equation is given -
f ( x ) = 3x² - 9x + 5 .
The leading coefficient is 3 .
The trailing coefficient is -9 .
Sum of roots -
=> - [ Leading Coefficient / Trailing Coefficient ]
=> - [ - 9 / 3 ]
=> 3
