If the degree of the equation is two, then the result leads to the quadratic equation. The following equations are entitled to the quadratic equations.
In the quadratic equation, the maximum power of the variable is 2. It consists of x², x, and the constant term.
Given
[tex]\rm 1.\ y =2 x^{2} \\2.\ y = 2x^{2} -8\\3.\ y = -2+2x-8\\4.\ y +3x = 2x^{2} -8\\5.\ y + 3x^{2} = 2x +3x^{2} -8[/tex]
If the power of x is 2, then it is said to be a quadratic equation.
1.
[tex]\rm y = 2x^{2}[/tex]
The above expression is a quadratic equation.
2.
[tex]\rm y= 2x^{2} -8[/tex]
The above expression is a quadratic equation.
3.
[tex]\rm y = 2x-10[/tex]
The above expression is not a quadratic equation.
4.
[tex]\begin{aligned} \rm y +3x &= 2x^{2} -8\\\rm y &= 2x^{2} -3x -8\\\end{aligned}[/tex]
The above expression is a quadratic equation.
5.
[tex]\begin{aligned} \rm y + 3x^{2} &= 2x +3x^{2} -8\\\rm y &= 2x-8\\\end{aligned}[/tex]
The above expression is not a quadratic equation.
Thus, the third and fifth are not quadratic equations and the first, second, and fourth are quadratic equations.
