A Quick Algebra Review - Hood College
www.hood.eduWhen solving absolute value equations, we must consider that the number inside could have been negative before you applied the absolute value! For example: │x + 2│= 3 x + 2 and x + 2 3 -3 When we take the absolute value, both are equal to 3. So we end up with TWO SOLUTIONS for this equation. -2(x – 5) < 10 -2 -2

For solving polynomial inequalities, the method will be used later when we consider where a function is increasing or decreasing as well as where a function is convex or concave. Students should note that there is a shortcut for solving inequalities, using the Intermediate Value

Divide by the positive value of the variable’s coefficient. Step 5. If the variable is negative, divide by –1 and reverse the sign. Solving Inequalities – Examples –2d + 3 < –7 1. –3 = –3 –2d ...
Solving inequalities - mathcentre.ac.uk
www.mathcentre.ac.ukSolving inequalities mc-TY-inequalities-2009-1 Inequalities are mathematical expressions involving the symbols >, <, ≥ and ≤. To ‘solve’ an inequality means to find a range, or ranges, of values that an unknown x can take and still satisfy the inequality. In this unit inequalities are solved by using algebra and by using graphs.
