When thinking about reinforcement, always remember that the end result is to try to increase the behavior, whereas punishment procedures are used to decrease behavior. For positive reinforcement, try to think of it as adding something positive in order to increase a response.

Which equation has exactly two real and two non real solutions?

tatiyna

Answer:

The first option $x^4-21x^2-100=0$ .

Step-by-step explanation:

To have exactly 2 real and two non real solutions, the degree of the polynomial must be a degree 4. Degree is the highest exponent value in the polynomial and is also the number of solutions to the polynomial. This polynomial ha 2 real+2 non real= 4 solutions and must be $x^4$ . This eliminates the bottom two solutions.

In order to have two real and two non real solutions, the polynomial must factor. If it factors all the way like

$x^4-100x^2=0\\x^2(x^2-100)=0\\x^2(x-10)(x+10)=0\\\\x^2=0\\x-10=0\\x+10=0$

This means x=0, 10, -10 are real solutions to the polynomial. It has no non real solutions. This eliminates this answer choice.

Only answer choice 1 meets the requirement.
