Recognising the Quadratic Equations

Quadratic Equations A quadratic Equation is an equation in which the highest power Of the variable in any term is two.

General Form of Quadratic Equation is ax²+bx+c=0 ( x is a variable , a,b and c are real number and a = 0

If an expression given, can you recognise whether it is a Quadratic Equation or not ?

Equation in the form of ax²+bx+c=0 and give the value of a, b and c 1. 3x(x+1)=1

3x²+3x=1 3x²+3x-1=0

2. x²=3x-7 x²-3x+7=0

General Form of Quadratic Equation where a=3, b= 3 and c=-1.

General Form of Quadratic Equation where a=1, b= -3 and c=7.

3. (x-3)(2x+5)=0 2x²+5x-6x-15=0 2x²-x-15=0

4. x(x-8)=-16 x²-8x+16=0

General Form of Quadratic Equation where a=2, b= -1 and c=-15

General Form of Quadratic Equation where a=1, b= -8 and c=16
