Select the two values of x that are roots of this equation . 2x ^ 2 + 1 = 5x

2x^2 + 1 = 5x

<=>

2x^2 - 5x + 1 =0

b= -5

Discriminant b^2 - 4ac = 5^2 -4 x 2 x 1 = 25 - 8 = 17

=> Option C and D are correct.

Hope this helps!

:)

which agrees with the last two options in the list of possible answers

(mark both)

Step-by-step explanation:

We start by re-writing the quadratic equation in standard form:

Which can be solved by using the quadratic formula for a quadratic

with parameters:

Therefore the two values are:

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !
