Find the difference.

(3x4 - 5x2 - 4) - (2x3 x2 + 1)

w

3x4 - 2x3 - 4x2-5

a

(3x4 - 5x2 - 4) - (2x3 x2 + 1) is equals to - 15

3x4 - 2x3 - 4x2-5 is equals to - 7

Step-by-step explanation:

1.) (3x4 - 5x2 - 4) - (2x3 x2 + 1)

3 x 4 = 12 5 x 2 = 10 12 - 10 = 2 2 - 4 = - 2

2 x 3 = 6 6 x 2 = 12 12 + 1 = 13

-2 - 13 = - 15

2.) 3x4 - 2x3 - 4x2-5 is eaquals to - 7

3 x 4 = 12 2 x 3 = 6 12 - 6 = 6 4 x 2 = 8

6 - 8 = - 2 - 2 - - 5 = - 7
