Paano Kalkulahin si Quadratic Inequality Solver
Ano ang Quadratic Inequality Solver?
Quadratic inequalities involve quadratic expressions with inequality signs (>, <, ≥, ≤). Solutions are intervals on the number line where the inequality holds true.
Pormula
ax² + bx + c > 0 (or <, ≥, ≤); solve roots and test intervals
Step-by-Step na Gabay
- 1Find roots of ax² + bx + c = 0
- 2Test intervals between roots to determine sign
- 3Write solution as union of intervals
Mga Nalutas na Halimbawa
