What is Square formula?

And a square is a special case of a rectangle that has its two adjacent sides being of equal length. Therefore, the area can be expressed as – Area of a rectangle = Length × Breadth. Area of square formula = Length × Breadth. Area of square formula = s × s = s²

How many solutions does y x2 7x 11 have?

The quadratic formula gives two solutions, one when ± is addition and one when it is subtraction. This equation is in standard form: ax^{2}+bx+c=0. Substitute 2 for a, 7 for b, and -11 for c in the quadratic formula, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.

How can you solve quadratic equation in one variable using completing the square method?

The Steps

  1. Step 1: Set your equation to 0.
  2. Step 2: Move your single constant to the other side.
  3. Step 3: Divide by the coefficient of the squared term if there is one.
  4. Step 4: Take the coefficient of your single x term, half it including its sign, and then add the square of this number to both sides.
