Question

How do you find the solutions of xsquared-2x=3?

Answer 1

Answer:

-1 and 3

Step-by-step explanation:

We need to solve "xsquared-2x=3"

The following version of xsquared-2x=3 has more appropriate format:

x² - 2x = 3

We need to put this into standard form for quadratic equations.  To accomplish this, subtract 3 from both sides, obtaining:

x² - 2x - 3 = 0

This factors as follows:  (x - 3)(x + 1) = 0.

The solutions are found by setting each factor = 0 separately and solving for x:  3 and -1.
