Answer 1

Answer:

no its not a quadratic equation

i think the question is also wrong

it cant be simplfied as well..

pls do recheck

hope this helps you..

Answer 2

: Required Answer

Given, that's A/q to question

➝ (x + 1)2 = 2(x – 3)

➢By using the formula for (a+b)2 = a2+2ab+b2

⇒ x2 + 2x + 1 = 2x – 6

⇒ x2 + 7 = 0

➝ Since the above equation is in the form of ax2 + bx + c = 0.

Therefore, the given equation is quadratic equation.
