Completing the square formula is the formula required to convert a quadratic polynomial orequationinto a perfect square with some additional constant. It is expressed as, ax2+ bx + c ⇒ a(x + m)2+ n, where, m and n are real numbers. ...
I found a fun YouTube video of the Fort Collins High School Math Department singing a parody of Taylor Swift’s song “blank space”. In the video they are teaching the steps for completing the square. It also addresses imaginary numbers for more complex problems. I think this could be a...
Example 1: Complete the square for the quadratic x 2 - 6x + 7 = 0 Our approach is nearly identical to our first problem; the main difference is that the arithmetic will be slightly more complex. Step 1: Since this equation is equal to zero step 1 is satisfied. (x +2) 2 = √1 ...
