Question

2x(2)²+1=2x-1
Check wheather this equation is quadratric equation

Answer 1

Answer:

$2x {2}^{2} + 1 = 2x - 1 \\ \\ 2x \times 4 + 1 = 2x - 1 \\ \\ 8x + 1 = 2x - 1 \\ \\ 8x - 2x = - 1 - 1 \\ \\ 6x = - 2 \\ \\ x = \frac{ - 2}{6} \\ \\ x = \frac{ - 1}{3}$

Therefore it is not a quadratic equations because in quadratic equations maximum degree of x is 2 .
