Question 398862: Hi. Can you please help me?
I need to solve the following equation when P(t) = 0....
P(t)=-t^4+9t^2+400
Thank you!

You can put this solution on YOUR website! There are NO SOLUTIONS to this equation, since any value raised to an EVEN power must be greater than or equal to 0. Then, if you add +400 to this quantity, the result will always be positive, NEVER equal to 0. NO SOLUTION!!
