Which of the following shows factoring of polynomials with difference of two squares? Choices:
⟩⟩ x2-2xy+y = (x-y)(x-y)
⟩⟩ 4a2 – b2 = (2a+b)(2a-b)
⟩⟩ 25m4+15m3 = 5m2 (5m2+3m)
⟩⟩ x2-x-2 = (x-2)(x+1)

need solution, hope someone answer this tricky question. ​

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
