Question

Select the two values of x that are roots of the given polynomial below.

x2 - 5x + 2

Answer 1

(x-5/2)^2=-2+25/4=17/4
(x-5/2)=+,-square root 17/4
X= 5/2+,-square root 17/4

Answer 2

i dont think those answers were right ktnguyen

Answer 3

slight error (5/2)^2 = 25/4 = 6 1/4 which is not the constant term 2...

Answer 4

use the general quadratic formula

\[x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}\]

and if x^2 - 5x + 2 = 0

then a = 1, b = -5 and c = 2

substitute and evaluate
