User: Which of the following equations has only one solution?

User: If (x + 1)(x - 3) = 12, then which of the following statements is true?

User: If (x + 1)(x - 3) = 12, then which of the following statements is true? x + 1 = 0 or x - 3 = 0 , x + 1 = 12 or x - 3 = 12 , x - 5 = 0 or x + 3 = 0

Weegy: The solution set of 2x2-3x=5 is either 3.5 or -.5, depending on context of question. sharpies|Points 8125|

User: What is the solution set of 2x^2 - 3x = 5?

Weegy: You need to factor 2x^2 +3x -9... you probably learned FOIL (First, Outside, Inside, Last)... [ you use that to find the two terms you can multiply...
2x^2 + 3x -9 = (2x-3)(x+3) = 0
So you need to find when one of the two terms = 0, because when you multiply anything by 0 you get 0...
(2x-3) = 0 when x = 1.5
(x+3) = 0 when x = -3
So x = 1.5 or x = -3 ] selymi|Points 8542|
