Answer:
14
Step-by-step explanation:
7( 8 - 6 ) = 7 ( 2 ) = 14
Following PEMDAS, you would begin with solving within the ( ). So being that m = 8 you plug that in. Then subtract 6 from 8 which would then give you 2. The multiply 7 by 2, which gives you 14.
The quadratic formula is...

your a will be in front of your x^2, b in front of your x, and c will be the number without an x. Plug those into the equation and you'll get two answers. That will be it
10/4= 2.5
5/2.5= 2
2 would be your first answer
32x2.5= 80
80 would be your second answer
