Answer:
What do you need to know its not compleate Do you want me to divide or what
Step-by-step explanation:
<span>(4x-2)×6(2x+7) =
</span>
(4x-2) <span>× 12x + 42 =
48x^2 -24x + 168x -84 = 0
</span>
<span>48x^2 +144x -84 = 0
a = 48 b = 144 and c = -84
and the solution is
x1=.5 and x2=-3.5
</span>
4: 28, 5: 40, 6: 54, 7: 70
