Question

find roots of the quadratic equation x²-2x+3.

Answer 1

Heya !!!



P(X) = X² - 2X - 3




=> X² - 3X + X - 3




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



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



=> ( X -3) = 0 OR ( X + 1) = 0



=> X = 3 OR X = -1



Hence,


3 and -1 are the roots of the quadratic polynomial X² - 2X - 3.
