• To simplify the polynomial

• To convert the polynomial into a linear equation

• To change the polynomial's degree

In the context of polynomial equations, what does 'u-substitution' help achieve?

• It changes the polynomial into a linear equation

• It simplifies the polynomial by reducing its degree

• It eliminates complex numbers from the equation

• It allows for easier factoring by substituting a variable

What is a common factor pattern seen in higher degree polynomials?
