WebMathHelp.com. Solving Absolute Value Equations. The absolute value is isolated on the left-hand side, so I can drop the bars and split the equation into its two cases: Case 1 ("plus"): x2 − 4 x − 5 = +7. x2 − 4 x − 12 = 0. ( x − 6) ( x + 2) = 0. x = 6, x = −2. So if the quadratic is positive, there are two solution values to the ...
