I need this right now, which 3 are expressions. A. -3

B. 8 + c < 7d

C. b/12 = 24/16

D. 2a^8

E. (10+7)(50+1)

B, D, E

Step-by-step explanation:

B, D, and E are sentences with a minimum of two numbers and at least one math operation, an expression.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

c. (3,2,6) is the answer.
