Find the value of the lesser root of x2 - 6x + 8 = 0.

A) -4
B) -2
C) 2
D) 4

The lesser root is 2..

Explanation:

x² - 6x + 8 = 0

x² -4x - 2x + 8 = 0

x(x - 4) -2(x - 4) = 0

(x - 2)(x- 4) = 0

x = 2 or 4

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%
