4. Solving Absolute Value Equations
Sign In
How many cases do we have after we remove the absolute value?
Solutions: p=0.25 and p=- 1.25
Number Line:
Before we can solve this equation, we need to isolate the absolute value expression using the Properties of Equality.
An absolute value measures an expression's distance from a midpoint on a number line.
lc 4p+2 ≥ 0:4p+2 = 3 & (I) 4p+2 < 0:4p+2 = - 3 & (II)
(I), (II): LHS-2=RHS-2
(I), (II): .LHS /4.=.RHS /4.
(I), (II): Calculate quotient
Both 0.25 and - 1.25 are solutions to the absolute value equation. Let's graph these solutions on a number line.
