    ➡ x² + 2x – 3 = 0

    ➡ x² + 3x – x – 3 = 0

    ➡ x(x + 3) – 1 (x + 3) = 0

    ➡ (x + 3) (x – 1) = 0

    ➡ x = -3 (or) x = 1

    Roots of Quadratic Equation are -3, 1.

    Answer:

    =X² + 2X – 3

    = X² + 3X – X – 3

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

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

    i.e X= -3 or X= 1

    ans : – 3, 1
