Question

Here’s the question to solve. Just do the question that has the chart

Answer 1

Step 1:

Write the equation

`x^4-x^3+3x^2\text{ - 9x }-\text{ 54 = 0}`

Step 2:

Use trial and error to find one the the factor

x - 3 is a factor

Because when you substitute x = 3, the result is zero

Hence, 3 is zero of the polynomial

Step 3

Use the long division
