Question

check whether the following are quadratic equations: x(x+3) +6 =(x+2) (x -2)

Answer 1

Answer:

it is not a quadratic equation

Step-by-step explanation:

x(x+3)+6=(x+2)(x-2)

${x}^{2} + 3x + 6 = {x}^{2} - 4$

=> 3x+10=0

$here \: the \: term \: a {x}^{2} \: do \: not \: exists$

so, it is not a quadratic equation

Answer 2

Answer:

your answer is here :-

x(x+3)+6=(x+2)(x-2)

x^2+3x+6=x^2-4

3x+6= -4

3x+10=0

it does not follow the law of quadratic equations

so , it is not quadratic equation
