Answer 1

Answer:

No

Step-by-step explanation:

(x+3)² - (x+2)² = 9

x² + 6x + 9 - x² - 4x - 4 = 9

2x - 4 = 0

∵ Highest degree = 1 ≠ 2

∴ It is not a quadratic equation

Answer 2

Answer:

No,it is not a quadratic equation.

Step-by-step explanation:

$(x + 3) ^{2} - (x + 2)^{2} = 9 \\ ( {x}^{2} + 9 + 6x) - ( {x}^{2} + 4 + 4x) = 9$

x^2+9+6x - x^2 -4 -4x = 9

Here, x^2 gets cancelled and not makes it a quadratic equation because x^2 is a necessary condition for a quadratic equation.
