i don't know how to solve this, any help is appreciated.
1. find the values of k such that
2. find the value of so that the equation has roots that are numerically equal but opposite in sign.
thank you so much.
Hello, princess_21!
Another approach to #2 . . .
The equation simplifies to: .2. Find the value of so that the equation
has roots that are numerically equal but opposite in sign.
Consider the Quadratic Formula: .
. . The roots will be equal and opposite in sign when
Hence: .
