Determine the number of possible positive and negative real roots; then use the rational root theorem to determine all of the possible roots of the equation: 4x^4+20x-2=0​

+- 1/4,1/2,1,2,4

5 solutions.

Step-by-step explanation:

so first we have to do this using the theorum we find all the divors of -2

so +-2, +-1/ +-2,+-1,+-4 so there would be 5 solutions.

+- 1/4,1/2,1,2,4

if my answer helps please mark as brainliest.

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
