Linear Inequalities - Exercise 2

Find the critical numbers of the inequality given below by solving x² - 4(x - 1) = 1. Then test intervals and find the solution interval or intervals. The Justification has been given - No further justification is needed.

STATEMENT

JUSTIFICATION

x² - 4(x - 1) ≥ 1
x² - 4(x - 1) = 1 is related equation

Given

Use Distributive Property, Factorization, Zero Product Law, and Division & Addition Properties of Equality to solve and find critical numbers.

Use the property: Critical Numbers Define Solution Interval Endpoints to test and determine solutions.
