Answer:

Use F.O.I.L method
First, Outter, Inner, Last

So:

5x*7x= 35x^2

5x*-6= -30x

7x*2= 14x
2*-6= -12

So just add it all up, combine like terms and you have your answer.

35x^2 -16x -12

Answer:

12x - 4

Explanation:

Add like terms.

5x + 7x = 12x

2 + (-6) = -4

Therefore, (5x + 2) + (7x - 6) = 12x - 4.
