About Theo:
The Indian Method of solving a quadratic equation is as follows:

step 1:
Move the constant term to the right side of the equation
step 2:
Multiply each term in the equation by four times the coefficient of the x^2 term
step 3:
Square the coefficient of the original x term and add it to both sides of the equation
step 4:
Take the square root of both sides
step 5:
Set the left side of the equation to the positive square root of the number on the right side and solve for x
step 6:
Set the left side of the equation to the negative square root of the number on the right side of the equation and solve for x

Answer 3

Method 1
x² - 2x - 13 = 0
x² - 2x + 1 – 14 = 0
x² - 2x + 1 = 14
(x – 1)² = 14
x – 1 = ± √14
x = 1 + √14 or x = 1 – √14
