**The expression (3x^2 + 5x - 12) - 2(x^2 + 4x + 9) is equivalent to which of the following?

x^2 - 3x - 30

Step-by-step explanation:

step 1: -9   +   -1   =   -10    

-3   +   -3   =   -6     

-1   +   -9   =   -10    

1   +   9   =   10    

3   +   3   =   6     

9   +   1   =   10

No two factors can be found

Trinomial can not be factored

step 2: ((3x2 + 5x) - 12) - 2 • (x2 + 4x + 9)

step 3: -30 + 1 = -29

-15 + 2 = -13

-10 + 3 = -7

-6 + 5 = -1

-5 + 6 = 1

-3 + 10 = 7

-2 + 15 = 13

-1 + 30 = 29

so the answer is x^2-3x-30

21/58.

hope to be marked brainliest

no one knows lol
