Multiply and simplify: (a-b)^2 pls

a² - 2ab + b²

Step-by-step explanation:

(a – b)² = (a – b)(a – b)

We can use the FOIL method of multiplying two binomials

First terms:          a × a = a²

Outer terms: (-b) × (-b) =                  b²

Inner terms:       -b × a =        -ab

Last terms:       a × (-b) =       -ab          

                            Sum = a² - 2ab + b²

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.

y/x of point b= y/x of point a
