The solution of the quadratic equation is the value of the variable that makes the equation zero. We can say these solutions as roots or zeroes.
There are three methods to solve the quadratic equations.
- Factorisation
- Completing the square
- Quadratic formula.
Based on this try to find the answer for the following:
1. Find the roots of the quadratic equation \(9x^2-3x-2=0\) by factorisation method.
2. Which of the following is a root of quadratic equation \(x^2-8x+16=0\)
3. The factors of the quadratic equation \(a^2x^2-3abx+2b^2=0\) are
4. A quadratic equation can have at most ______ roots
