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

a=r

d=q

c=p

b=s

hope this !

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,
