Please, let this be a normal field trip [Wanda:] With the Friz? [Kids:] No way! [Arnold:] Oh!

1. x= 5, x=1

2. x= -4, x=2

3. x= -6, x=7

4. x= -7, x=5

5. x= -9, x=0

Step-by-step explanation:

You do the X factoring-

1.

A   B   C

x²+6x+5

(A)(C) and B

(1)(5)=5      6

Then figure out what two numbers multiply to get 5

but also add to 6. In this case, it would be 5 and 1

5x1= 5 and 5+1= 6

so it is:

x= 5, x= 1

Hope this helps!

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)
