Question

x(x+3) +5=(x+2) (x-2) is it a quadratic equation?
​

Answer 1

$\large{\mathtt{\red{\underbrace{\overbrace{\blue{\boxed{\boxed{\pink{«Answer»}}}}}}}}}$

=> x(X+5)+5=(X+2)(x-2)

=> x²+5x+5 = x²-2²

=> x²+5x+5 = x²-4

=> x²-x²+5x+5+4 = 0

=> 5x+9 = 0

Ans. No, it's not a quadratic equation

Answer 2

Answer:

given that X(X+3)+5=(X+2)(X-2)

then after solving this we find 3x +9

but according to the rolls this is not a quadratic equation.
