SOLVING QUADRATIC INEQUALITIES (Grade 9 Mathematics)

[@dominicperin7035]

Sir cau give an exam like this x² + 9x greater than or equal to -14

[@sirgleantv2344]

lipat mo lang sa kabila ng inequality yung -14 kaya magiging x² + 9x + 14 ≥ 0 na sya. then tsaka mo follow yung procedure. :)

Pano naman po kapag 2x² + 9x ≥ 5

[@sirgleantv2344]

@@dominicperin7035 ganun din. lipat mo sa kabila yung 5 kaya magiging 2x² + 9x - 5 ≥ 0 then tsaka mo follow yung procedure. the factors will be (x+5)(2x-1)=0
