PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!! I CANNOT RETAKE THIS!!

Answer: x = {-3, -1, 1, 7}

<u>Step-by-step explanation:</u>

f(x) = x⁴ - 4x³ - 22x² + 4x + 21

possible roots are: +/- 1, 3, 7, 21

Let's try x = 1

1  |  1     -4     -22       4       21

  <u>|  ↓      1       -3     -25     -21 </u>

     1     -3      -25    -21       0     <em>remainder is 0 so (x - 1) is a factor</em>

(x - 1)(x³ - 3x² - 25x - 21)

Next, let's try x = -1

-1  |  1     -3     -25      -21

   <u>|  ↓     -1        4        21 </u>

      1     -4      -21       0     <em>remainder is 0 so (x + 1) is a factor</em>

(x - 1)(x + 1)(x² - 4x - 21)

Then, factor the third polynomial

(x - 1)(x + 1)(x + 3)(x - 7)

Now, set each factor equal to zero and solve each one.

(x - 1) = 0    ⇒     x = 1

(x + 1) = 0   ⇒     x = -1

(x + 3) = 0   ⇒    x = -3

(x - 7) = 0   ⇒     x = 7
