What are inequalities in quadratic equation.
Answers
Answer:
Step-by-step explanation:
A quadratic inequality is simply a type of equation which does not have an equal sign and includes the highest degree two. Solving quadratic inequalities is same as solving quadratic equations.
quadratic inequality
A quadratic inequality is an equation of second degree that uses an inequality sign instead of an equal sign.
The solutions to quadratic inequality always give the two roots. The nature of the roots may differ and can be determined by discriminant (b2 – 4ac).
The general forms of the quadratic inequalities are:
ax2 + bx + c < 0
ax2 + bx + c ≤ 0
ax2 + bx + c > 0
ax2 + bx + c ≥ 0
Examples of quadratic inequalities are:
x2 – 6x – 16 ≤ 0, 2x2 – 11x + 12 > 0, x2 + 4 > 0, x2 – 3x + 2 ≤ 0 etc.
