Question

which of the following is not a quadratic equation
A. 2(x-1)²= 4x²- 2x + 1
B. 2x- x² = x² +5
C. (√2x+3)² + x² = 3x²- 5x
D. (x²+2x)² = x² +3 + 4x³​

Answer 1

Answer:

A)   2(X-1)² = 4X²-2X+1

Step-by-step explanation:

on solving this equ. we don't get the quadratic equ.

2(x-1)² = 4x²-2x+1

(2x-2)² = 4x²-2x+1

4x²+4-8x = 4x²-2x+1

4-1 = 2x+8x

3 = 10x

x = 3/10

or x = 0.3
