Plz me by the end of the day lisa solved 3x2 + 1 = 28 as shown. 3x2 + 1 = 28 3x2 = 27 x2 = 9 she concluded that the solutions to this quadratic equation are x = -9 or x = 9. what are the correct solutions to this quadratic and how did you arrive at your answer?

Step 1 : subtract 1 from both sides

Step 2 : Divide both sides by 3

Step 3 : Find the square root of 9

x= (-3,3)

remember negative × negative = positive
