Factor 6x^4 - 5x^2+12x^2-10 by grouping. what is the resulting expression?

Factorized form of the expression will be (x² + 2)(6x²- 5).

Step-by-step explanation:

In the given expression we have to factorize it by grouping.

For which we will divide the expression in 2 groups as below.

=

Now we take the common terms x² from first term and 2 from second group.

= x²(6x² - 5) + 2(6x² - 5)

= (x² + 2)(6x² - 5)

Therefore, resulting expression after factorization will be (x² + 2)(6x² - 5)

15%

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%

you.
