Question

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

Answer 1

Hey

Here is your answer,

( X-2 ) ( x+1 ) = ( x-1 ) ( x+3 )
X^2 + x - 2x - 2 = x^2 + 3x - x - 3
-x - 2 = 2x - 3
-x - 2x = -3+2
-3x = 1
X = -1/3

Hope it helps you!

Answer 2

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



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




X² + X - 2X - 2 = X² + 3X - X - 3






X² - X² - X - 2X - 2 + 3 = 0





-3X + 1 = 0





X = 1/3
