To factor the polynomial 2x54x3+2x and solve the equation 2x54x3+2x=0, we can start by factoring out the common term.

  1. Factor out the GCF (Greatest Common Factor): 2x54x3+2x=2x(x42x2+1)

  2. Set the factored polynomial equal to zero: 2x(x42x2+1)=0

    This gives us one solution immediately: 2x=0x=0

  3. Now, we need to solve x42x2+1=0. Let's make a substitution y=x2: y22y+1=0

    This factors as: (y1)2=0

    Hence, we find: y1=0y=1

    Substituting back gives: x2=1x=1orx=1

  4. Collecting all the solutions: The potential solutions are: x=0,x=1,x=1

Therefore, the final factored form of the polynomial and the solutions to the equation 2x54x3+2x=0 are x=0,x=1,x=1.

The correct response is: x = −1, x = 0, x = 1.
