How to solve a polynomial cubed
WebStep 1: Find a root, say 'a', of the cubic polynomial. Then (x - a) is the factor. (This can be one of the prime factors of the constant term of the polynomial) Step 2: Now, divide the linear factor by the cubic polynomial to find a quadratic factor of the polynomial. WebStep 1: Use the factor theorem to test the possible values by trial and error. f (1) = 2 + 3 – 11 – 6 ≠ 0 f (–1) = –2 + 3 + 11 – 6 ≠ 0 f (2) = 16 + 12 – 22 – 6 = 0 We find that the integer root is 2. Step 2: Find the other roots either by inspection or by synthetic division. 2x 3 + 3x 2 – 11x – 6 = (x – 2) (ax 2 + bx + c) = (x – 2) (2x 2 + bx + 3)
