Question

If using the method of completing the square to solve the quadratic equation

2? + 4x + 3 = 0, which number would have to be added to "complete the square"?

Answer 1

Step 1 Divide all terms by a (the coefficient of x2). Step 2 Move the number term (c/a) to the right side of the equation. Step 3 Complete the square on the left side of the equation and balance this by adding the same value to the right side of the equation.

Answer 2
