Solve x 4 - 11x 2 + 18 = 0.
**Weegy:** x=11 **User:** If P(x) = 2x 4 - x 2 + 3x - 1, use synthetic division to find P (2).
**Weegy:** (3x-2) squared is 9x^2 - 12x + 4. **User:** 9x^2 - 12x + 4. **User:** Determine the rational roots of 2x 5 - 11x 4 + 14x 3 - 2x 2 + 12x + 9 = 0.

x^4 - 11x^2 + 18 = 0

(x^2 - 2)(x^2 - 9) = 0

(x + sqrt 2)(x - sqrt 2)(x + 3)(x - 3) = 0

x = - sqrt 2, x = sqrt 2, x = -3 or x = 3

(x^2 - 2)(x^2 - 9) = 0

(x + sqrt 2)(x - sqrt 2)(x + 3)(x - 3) = 0

x = - sqrt 2, x = sqrt 2, x = -3 or x = 3

P(x) = 2x^4 - x^2 + 3x - 1

P(2) = 2(2^4) - 2^2 + 3(2) - 1

= 2(16) - 4 + 6 - 1

= 32 - 4 + 6 - 1

= 28 + 6 - 1

= 34 - 1

= 33

P(2) = 2(2^4) - 2^2 + 3(2) - 1

= 2(16) - 4 + 6 - 1

= 32 - 4 + 6 - 1

= 28 + 6 - 1

= 34 - 1

= 33
