a.
Show that the sum of the two solutions of the equation
The sum of the two solutions is
Given:
The equation is,
Concept Used:
- The sum of the zeroes is equal to the negative of the coefficient of x by the coefficient of x2.
- The product of the zeroes is equal to the constant term by the coefficient of x2.
Calculation:
The sum of two solution of equation is −
So the sum of the two solutions of the equation is
b.
Show that the product of the two solutions of the equation
The product of the two solutions is
Given:
The equation,
Concept Used:
- The sum of the zeroes is equal to the negative of the coefficient of x by the coefficient of x2.
- The product of the zeroes is equal to the constant term by the coefficient of x2.
Calculation:
The product of two solution of equation is −
So the product of the two solutions of the equation is
