Answer 2

Answer:

We get x(x+1)+8=(x+2)(x-2) is not a quadratic equation.

Step-by-step explanation:

• As per the question we have to evaluate the given data.

        Given data:- x(x+1)+8=(x+2)(x-2).​

        To find:- Check whether the quadratic equations x(x+1)+8=(x+2)(x-2).​

        Solution:-

• A quadratic equation is an algebraic expression of the second degree in x.
• The quadratic equation in its standard form is $ax^{2} +bx+c=0.$
• where a, b are the coefficients, x is the variable, and c is the constant term.

        so that,

         $x(x+1)+8=(x+2)(x-2)\\=>x^{2} +x+8=x^{2} -4\\=>x+12=0$

 No degree of 2 is present in this equation so this equation is not a quadratic equation.
