# Solve x4 – 17×2 + 16 = 0. Let u = Select all of the zeroes of the function. i i

A latter academics question and answer asked students to declare what they consider is the main important challenge for a student to do to be able to get success. A lot of results, one that that stood out was practice. Successful persons are certainly not born successful; they become successful via hard work and dedication. This is how you can achieve your goals. shown below are one of the answer and question example that you would probably utilize to practice and boost your practical knowledge and also give you insights that will assist you to maintain your study in school.

## Question:

Solve x4 – 17×2 + 16 = 0.
Let u =
Select all of the zeroes of the function. i i

The zeros of the equation are 4 and -4

Given the polynomial expression x^4 – 17x^2 + 16 = 0.

Reduce the function to a quadratic function

Let P = x²

The equation becomes;

(x²)² – 17x² + 16 = 0

P² – 17P + 16 =0

Factorize the result

P² – 16P – P+ 16 =0

P(P-16)-1(P-16) = 0

(P-16) (P-16) = 0

P = 16 twice

Since P = x²

x² = 16

x = ±√16

x = ±4

Hence the zeros of the equation are 4 and -4

They could simply hopefully guide the student handle the question by obtaining the questions and answer examples. You may possibly then have a discussion with your classmate and continue the school learning by studying the subject alogside each other.
