Answer to Problem 82HP
Only the term with coefficient of x has changed its sign when sign of roots are switched.
Explanation of Solution
Given information:
The two random roots of the quadratic equation.
Formula used:
The standard form of the quadratic equation is
Calculation:
Consider the roots of the quadratic equation that are
Recall that standard form of the quadratic equation is
Apply it,
When sign of roots are switched,
Consider the roots of the quadratic equation that are
Recall that standard form of the quadratic equation is
Apply it,
Thus, only the term with coefficient of x has changed its sign when sign of roots are switched.
