(x - 2)² + 1 =2x-3
Using (a - b)² = a² + b² - 2ab
(x² + 4- 4x) + 1 = 2x - 3
x² + 5-4x = 2x - 3
x² +5 4x-2x + 3 = 0
x² - 6x + 8 = 0
It is the form ax² + bx+c = 0
Where, a = 1, b = -6, c = 8
Hence it is a quadratic equation.
hope it helps..

Answer:
Quadratic equation
Step-by-step explanation:
(x-2)² + 1 = 2x-3
=> x²-4x+4+1 = 2x-3
=> x²-4x+5 = 2x-3
=> x²-4x-2x+5+3 = 0
=> x²-6x+8 = 0
Therefore, it is a quadratic equation as the highest power is 2.
