Answer 1

Given question -:

which of the following equation are quadratic equation (x - 1)=2x2 +x

let's try to solve the question

$( x - 1) = 2 {x}^{2} + x$

$x - 1 - 2 {x}^{2} - x = 0$

$- 2 {x}^{2} - 1 = 0$

$- (2 {x}^{2} + 1) = 0$

$2 {x}^{2} + 1$

Hence the above equation is in the form of quadratic equation as above equation is In the form of

${a}^{2} + bx + c \: \\ where \: x \: is \: not \: equals \: to \: 0$
