Answer:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
0-(2*x^3-4*x^2-34*x+68)=0
Step by step solution :
STEP
1
:
Equation at the end of step 1
0-((((2•(x3))-22x2)-34x)+68) = 0

Pulling out like terms
4.1 Pull out like factors :
-2x3 + 4x2 + 34x - 68 =
-2 • (x3 - 2x2 - 17x + 34)
Checking for a perfect cube :
4.2 x3 - 2x2 - 17x + 34 is not a perfect cube
