Mrs. A explains how to factor polynomial functions of degree higher than two, focusing on a degree 4 polynomial. The process begins with identifying common factors, followed by using the factor theorem to find polynomial factors. She demonstrates long division to verify factors and concludes with factoring a quadratic expression using decomposition. The video provides a step-by-step guide to simplifying and factoring complex polynomials.

What is the first step in factoring polynomials of degree higher than two?

• Apply the Factor Theorem

• Perform polynomial long division

• Extract common factors

• Use the quadratic formula

What is the common factor extracted from the polynomial in the tutorial?

• None of the above

• 3x

• 2x

• x

What does the Factor Theorem state about polynomial factors?

• None of the above

• If x - a is not a factor, then substituting a will zero the polynomial

• If x - a is a factor, then substituting a will zero the polynomial

• If x - a is a factor, then substituting a will not zero the polynomial

How do you verify if x - a is a factor of the polynomial?

• None of the above

• Multiply x - a by the polynomial and check for zero

• Divide the polynomial by x - a and check for a non-zero remainder

• Substitute a into the polynomial and check if the result is zero
