Question

(x-2)(x-1)=x²+2 is this a quadratic equation?

Answer 1

Answer:

the given equation is not a quadratic.

Step-by-step explanation:

(x-2)(x-1)=$x^{2}+2$

$x^{2}$-x-2x+2=$x^{2}$+2

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

$x^{2}$-$x^{2}$-3x+2-2=0

0-3x+0=0

3x=0

it is not of the form a$x^{2}$+bx+c=0

hence, it is not a quadratic equation.
