Solve the equation by using the Quadratic Formula. x^2-2x-3 = 0
Added by Heather L.
Step 1
So we can substitute these values into the formula: x = (-(-2) ± √((-2)^2 - 4(1)(-3))) / 2(1) Simplifying: x = (2 ± √(4 + 12)) / 2 x = (2 ± √16) / 2 x = (2 ± 4) / 2 So the solutions are: x = (2 + 4) / 2 = 3 x = (2 - 4) / 2 = -1 Show more…
