X2-x+3x-3=0

X(x-1)+ 3(x-1) =0

x=-3 and X=1
please mark brainlist

Answer 2

AS GIVEN : x² + 2x -3 = 0

SO BY

SPLITTING THE MIDDLE TERM..

=» x ² - 3x +1x - 3 = 0

=»Taking X in given equation :::

=» x ( x - 3 ) + 1( x - 3 ) = 0

=»( x + 1 )( x - 3 ) = 0

THEREFORE THE FACTORS ARE : -

- 1 & 3

HOPE THIS HELPS..
