Multiply.
(2x2 – 3x + 5)(x2 + 4x + 1)
o a. 2x4 + 2x2 - 12x + 5
o b. 2x4 - 12x2 + 5
c. 3x2+x+6
d. 2x4 + 5x3 – 5x2 + 17x + 5

good luck!

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
