Question

check wheather the following is quadratic equation
(x+1)³=2(x-3) ​

Answer 1

Answer:

Step-by-step explanation:

Given that,

( x + 1 )³ = 2 ( x - 3 )

⇒x³ + 1³ + 3 (x)² (1) + 3 (x) (1)² = 2x - 6

⇒ x³ + 1 + 3x² + 3x - 2x + 6 = 0

⇒ x³ + 3x² - x + 7 = 0

Hence, it is not a quadratic equation,it is a cubic equation.
