QUADRATIC EQUATION
QUADRATIC
EQUATION
Quadratic or not. Solve for the roots of the each equation.
1. x²-3x-4 = 0.
2. (x+1)²=0
3. 11= 2x²
4. 9x- 1= 0
5. 4x²-1=0
The Standard Form of Quadratic Equation is:
ax²+bx+c =0
In the equation ax²+bx+c =0 , ax² is the
quadratic term, bx is the linear term,
and c is the constant term.
Example of Quadratic equation in the form of ax²+bx+c =0
- x² + x – 4 = 0
- x² -3x - 2 = 0
- x² +18x+80 = 0
is an equation of the second degree, meaning it contains at least one term that is squared.
Where a, b and c
are real numbers
and a ≠ 0.
Example of Quadratic equation in the form of ax²+c =0
- 2x²-10 = 0
- 3x²+ 1=0
- -10+5x =0
- 11x= -9
- 4x+5=0
When b=0 in the equation ax²+bx+c =0, it
results to a quadratic equation of
the form ax²+c =0
