Question

Q-1) check whether the following are quadratic equations :
i) (x+1)² = 2 (x–3) .
ii) x²–2x = (–2) (3–x) .
iii) (x–2) (x+1) = (x–1) (x+3) .​

Answer 1

Step-by-step explanation:

i) It is a quadratic equation since the degree of the polynomial is 2.

ii) It is also a quadratic equation since the degree of the polynomial is 2.

iii) It is not a quadratic equation since on solving the degree of the polynomial is 1.
