Question

check weather the equation is quadratic or not (x+1)3 =2(x-3)​

Answer 1

Answer:

(X+1)3

=x=3-1

=x=2 and

yes,the answer is right.

Answer 2

Answer:

(x+1)² = 2(x-3)

by using formula :

(a+b)² = a²+b²+2ab

= x²+1²+2(x)(1) = 2x - 6

= x² + 1 + 2x = 2x - 6

= x² + 1 + 2x - 2x + 6 = 0

= x² + 7 + 0x = 0

= x² + 0x + 7 = 0

= x² + 7 = 0

it is of the form of ax²+bx+c = 0

hence the given equation is quadratic equation .

Hope it helps
