Given equation,
(x+1)²=2(x-3)
Converting it into ax²+bx+c=0,
x²+2x+1=2x-6
→x²+7=0
As it would should be a quadratic equation,
It would be x²+0x+7

Answer:
The value of 'x' is ±√-7
Step-by-step explanation:
Given (x+1)² = 2(x-3)
We know that (a+b)² = a²+b²+2ab
(x+1)² = x²+1²+2(1)(x)
= x²+1+2x
and 2(x-3) = 2x - 6
Now put the above values in given expression then
(x+1)² = 2(x-3)
x²+1+2x = 2x-6
x²+1+2x-2x+6 = 0
x²+7 = 0
x² = -7
x= ±√-7
Therefore, x= ±√-7.
