of the equation experience. Post Y Sprint was 10 x minus 14. Why minus seven equals zero would sort this out. So our exes are together. Are wise air together we're in and seven to both sides. Now this is leaving room to complete the square half of tennis. 55 spurs, 25 at it. The right side as well. Half of negative 14. This negative sevenths. Where is positive? 49. So at another 49 of the right hand side, this allows us to write perfect square by no meals X plus five square plus why minus seven square in seven plus 25 miles 49 81 which tells us at the center of this circle is at negative five Positive seven in the radius is nine because nice.
