Question

( x-2 ) ( x+1 ) = ( x-1 ) ( x+3 )

Answer 1

Answer: Given equation,( x-2 ) ( x+1 ) = ( x-1 ) ( x+3 )

Not a quadratic equation

Step-by-step explanation:

Given equation,( x-2 ) ( x+1 ) = ( x-1 ) ( x+3 )

$x^{2} +x-2x-2=x^{2} +3x-x-3$

$x^{2} -x-2=x^{2} +2x-3$

$x^{2} -x^{2} +x-2x-3x+x-2+3=0$

-3x+1=0

Given equation is not a quadratic equation. Because, the equation doesn't have the degree of 2.So, this is not a quadratic equation. A polynomial when equated to zero or some value becomes an equation
