Define Quadratic equation.
An equation which have highest degree of variable x or y is square.in quadratic equation a,b and c are real numbers and a not equal to zero.
standard form of quadratic equation .
the standard form of quadratic equation is ax2 + bx + c = 0where a,b and c are coefficients or contents and x is known as variable(an unknown term)
it is a standard form of quadratic equation in x variable but if we written the standard form of quadratic equation in y variable the it will be in this form ay2 + by + c = 0
Method to solve the quadratic equation.
there are three main and simple methods to solve the quadratic equation.
1- Factorization method.
2-Completing square method.
3- Method of quadratic formula.
examples of standard form of quadratic equation equation.
1 - 3x2 + 10x + 7 = 0
2 - 6x2 + 7x + 2 = 0
3 - 7x2 _ 6x + 1 = 0
4 - a2x2 + abx - 2b2 = 0
