x^2 + 2x - 3 = 0
x^2 + 2x = 3
x^2 + 2x + 1 = 3 + 1
x^2 + 2x + 1 = 4
(x + 1)^2 = 4
x + 1 = (+-) sqrt 4
x = -1 (+-) 2

x = -1 + 2 = 1
x = -1 - 2 = -3

so x = 1 and -3

The solution of the equation is -3,1.

What is a Quadratic Equation?

A quadratic equation is an equation that can be written in the form,

ax²+bx+c = 0.

The equation is x²+2x-3 = 0

To solve it has to be broken down into factors

x² +2x +1 -1 -3 = 0

(x +1)² -4 = 0

(x+1)² = 4

x+1 = [tex]\rm \pm[/tex] 2

x+1 = +2

x = 1

x+1 = -2

x = -3

Therefore, the solution of the equation is -3,1.
