Which shows two expressions that are equivalent to (Negative 8) (negative 12) (2)?
(Negative 96) (2) and (Negative 8) (negative 24)
(Negative 8) (negative 24) and (Negative 1) (192)
(Negative 96) (2) and (Negative 1) (192)
(Negative 8) (Negative 24) and (Negative 16) (Negative 12)

where's the diagrams?

just get this app called photo math it should be able to do those

x^2 + 81

we can factor this using difference of square binomials.

rewrite the equation:

x^2 - (-81)

factor:

(a^2 - b^2) = (√a^2 + √b^2)(√a^2 - √b^2)

(x^2 - (-81) = (x + √-81)(x - √-81)

we can remove the - from under the radical by multiplying it by i.

(x^2 - (-81) = (x + i√81)(x - i√81)

(x^2 - (-81) = (x + 9i)(x - 9i)

we can check our answer by using foil:

x^2 - 9ix + 9ix - 81i^2

x^2 - 81^2

i^2 = -1

x^2 + 81
