True or false:
The solution, root, x-intercept, and zero of a problem are all the same thing.

• True
• False, because the solution and root are the same but the x-intercept and zero are different
• False, because the x-intercept and root are the same but the zero and solution are different
• False, they are all different

• p = -1, 1, -2, 2, -3, 3,

Give P(x) = -4x² + 3x³ - 17x + 6

As all possible zeroes = p/q =  $\pm$ {factor of constant/factor of leading coefficient}

• All possible zeroes =

   $\pm$ {1, 2, 3, 6, 1/1, 1/4, 2/1, 2/4, 3/1, 3/2, 3/4, 6/1, 6/2, 6/4}

• All possible zeroes =

   $\pm$  {1, 2, 3, 6,1/3, 2/3}

• All possible zeroes =

   $\pm$ {1, 2, 4, 1/2, 1/3, 1/6, 2/3, 4/3}

• All possible zeroes =

   $\pm$ {1, 2, 4, 1/2, 1/3, 1/6, 2/1, 2/2, 2/3, 2/6, 4/1, 4/2, 4/3, 4/6}

Find all the p/q factors for:
 $f\left(x\right)=2x^4-3x^3+5x+25$
