Please try to follow me, as I demonstrate a method of solution.
This could get complicated. I'll try to go slowly, and you must
stop me if I do anything that's not clear.
Ready ?
You said that -5c/8 = 20
Multiply each side by 8: -5c = 160
Divide each side by 5 : - c = 32
Multiply each side by -1 : c = -32
Answer:
-2x^4+x^3-5x+8
Step-by-step explanation:
8-5x+x^3-2x^4
Write the polynomial from highest powers of x to lowest
-2x^4+x^3-5x+8
All you need to do is solve it

or

When solved your answer is
0.25 or 1/4
------------------------
What I did to solve it was....
1. Divide top fraction by bottom fraction to get decimal
1 ÷ 2 = 0.5
2. Then multiply 0.5 by its self (the same as putting it to the ^2)
0.5 x 0.5 = 0.25
Which one is the one you want, 781:-:(divison)26?
Answer:
x=2
Step-by-step explanation:
5-3=2
x=2
