Question

`x { }^(2) + 2x - 3`
​

Answer 1

x = 1 or x = -3

Explanation:

Solve for x:

x^2 + 2 x - 3 = 0

The left hand side factors into a product with two terms:

(x - 1) (x + 3) = 0

Split into two equations:

x - 1 = 0 or x + 3 = 0

Add 1 to both sides:

x = 1 or x + 3 = 0

Subtract 3 from both sides:

Answer: x = 1 or x = -3
