Correct the error in the following equation. y=x² +18x +71 y-71 = x2 - 18x – 18 y-71 - 18 = (x-9) y=(x-9)2 +89 A. The equation is correct. B. y-71- 18 = (x – 9) should have been y-71- 18 = (x–9)(x +9) instead. C. X? - 18x - 18 should have been x2 + 18x + 81 instead. D. The solution should be y= (x +9)2 +89 instead.
