Answer:
More than 6.8 yards per game.
Step-by-step explanation:
Let x be the possible number of yards per play for the winning team.
We have been given that the winning team had 80 offensive plays, so the number of possible yards in 80 offensive plays will be 80x.
We have been given that a winning football team more than doubled the offensive yards gained by its opponent.
We can represents this information in an inequality as:
Therefore, the inequality can be used to find the possible number of x of yards per play for the winning team.
Let us solve for x.
Let us divide both sides of our inequality by 80.
Therefore, the winning team will score more than 6.8 yards per play.

Answer:
x = -0.62 and x = 4.29
These values are approximations !
Step-by-step explanation:
You can not use Factoring to solve this equation. Perhaps you did not use the exact notation as in the original question?
Anyway, to solve it, you can still use the ABC formula.
3x²-11x-6=0
a = 3
b =-11
c = -6
x = [11 + √{121 -4(3 *-6)} ]/ 2*3
x = [11 + √{121 -4(-24)} ]/ 6
x = [11 + √{121 + 96} ]/ 6
x = [11 + √{217} ]/ 6
x = 4.29 This is an approximation !
x = [11 - √{121 -4(3 *-6)} ]/ 2*3
x = [11 - √{121 -4(-24)} ]/ 6
x = [11 - √{121 + 96} ]/ 6
x = [11 - √{217} ]/ 6
x = -0.62 This is an approximation !
