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:

2x3 – 6x2 – 14x + 24 square centimeters

if i'm wrong i'm sorry : )

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
