Best ResponseYou've already chosen the best response.1ok, lets go step by step, x^2 8x = 5 what did you add to both sides of this equation?

Best ResponseYou've already chosen the best response.1good! so left side became the perfect square of (x4) \((x4)^2 = 165 \\ (x4)^2=11\) now take square root on both sides

Best ResponseYou've already chosen the best response.0okay but my answer choices are x = negative four plus or minus the square root of eleven x = four plus or minus the square root of eleven x = negative four plus or minus the square root of five x = four plus or minus the square root of five
