WebIn solving quadratic equalities Sal was showing how to solve for f (x) = 0. Meaning the points at which the f (x) line crosses or intersects the x-axis (=0). In solving quadratic INequalities Sal shows how you can solve for f (x) > 0 or f (x) < 0. Meaning the x coordinates at which point the f (x) line is above (>) or below (<) the x-axis (0). WebSep 27, 2024 · Start the solution process as before, and at the end, you can move the variable to the left to write the final solution. Divide both sides by − 12 to isolate the variable. Since you are dividing by a negative number, you need to change the direction of the inequality sign. − 1 2 > − 12x − 1 2 − 12 > − 12x − 12.
