Question 304015: How do you do a quadratic equation with the method from India. It starts off with moving the constant term to the right side of the equation and then multiplying each term by 4. In step 3 it tells you to square the co-efficient of the original x term and add it to both sides of the equation. After this point, I get lost because it asks to take the square root of both sides.
