Question 179376: An original quadratic equation for x is of the form: x^2+bx+c=0. If c is increased by 4, the roots for x of the resulting equation are equal, but if the original c is decreased by 5 one of the roots for x in this resulting equation is twice the other. Find the product of the roots for x in the original quadratic equation. Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! If the roots are and , I can write
the original equation is of the form
(1)
(2)
Subtract (1) from (2)
The product of the roots is 14
check:
(1)
OK
