Answer 2

To solve the equation, we need to let u = x²

What is a quadratic equation?

A quadratic equation is an algebraic expression that takes the power of the second degree.

From the given parameter:

• x⁴ - 17x² + 16 = 0

For us to be able to solve the given equation, we need to reduce the equation to a quadratic form.

This can be achieved by making an assumption that:

• u = x²

So, we will replace x² with u in the given equation.

By doing so, we have:

• u² - 17u + 16 = 0
