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 ...
Example: Complete the square given the equation 4x2+4y2−24x+32y−4=04x2+4y2−24x+32y−4=01) Do the squared terms have matching coefficients? Yes. So, we have a circle here.2) Can we make the squared terms have a coefficient of 1? Yes, we can do this. How? By dividing...
