Question

QUADRATIC EQUATIONS :

1.( x-2) ( x + 1) = ( x -1) ( x+ 3)
2. ( x + 1) ^2 = 2 ( x - 3)​

Answer 1

Answer:

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

   x² + x - 2x - 2 = x² + 3x - x - 3

   x² - x - 2 = x² + 2x - 3

  x² - x  - x² - 2x = -3 + 2

   -3x  = -1

   x = 1/3

2. ( x + 1)² = 2 ( x - 3)​

   x² + 1 + 2x = 2x - 6

   x² + 1 + 2x - 2x + 6 = 0

   x² + 7 = 0

   x² = -7

   x = √-7

   x = √7i
