Determine the values for which x27x+100

A.

2 x 5

B.

-2 x 3

C.

-2 x 3

D.

2 x 5

Correct answer is D

Explanation

x27x+100

Solve for x27x+10=0

We have, (x - 5)(x - 2) 0.

Conditions:

Case 1: (x - 5) 0, (x - 2) 0.

x 5; x 2.

2 x 5.

Choosing x = 3,

32 - 7(3) + 10 = 9 - 21 + 10

= -2 0.

2 \leq x \leq 5.
