Question

Select the two values of x that are roots of the given polynomial below. x^2=3x-5

Answer 1

Welcome to OpenStudy, pashes!

Although you could just try the given x values in the list of possible answers, why not get practice in actually solving quadratics? If x^2=3x-5, then \[x^2- 3x + 5 = 0\]

Answer 2

Unfortunately, this doesn't have nice integer roots; that means we'll need to use the Quadratic formula to find the two roots. Have you used the Q. F. before?

Note that in \[x^2- 3x + 5 = 0\] a=1, b=-3, and c=5.
