when directed to solve a quadratic equation by completing the square, Sam arrived at the equation (x-(5/2))^2= (13/4). which equation could have been the original equation given to Sam?
We have the following expression: (x- (5/2)) ^ 2 = (13/4) Let's rewrite the given expression: x ^ 2 - 5x + 25/4 = (13/4) x ^ 2 - 5x + 25/4 - 13/4 = 0 x ^ 2 - 5x + 12/4 = 0 x ^ 2 - 5x + 3 = 0 Answer: the original equation given to Sam could have been: x ^ 2 - 5x + 3 = 0
