Question

& Check whether x-3x + 5x = (x- 2) is quadratic equation or not.​

Answer 1

$\huge\mathfrak\blue{Answer:-}$.

x-3x+5x=x+2

x-8x=2+x

-7x=2+x

-7x-x=2

-8x=2

x=2/-8

x=1/-4 { Thus it's not a quad equation}

Answer 2

$x-3x + 5x = (x- 2)\\\\x - 2x = x - 2 \\\\- x = x -2 \\\\-x -x = -2 \\\\-2x = -2 \\\\x = \frac{-2}{-2} \\\\x= 1 \\\\no , its \ not \ a \ quadratic \ equation ...\\\\hope \ it \ helps \ !!$
