To solve this I'm going to split the middle term.
First multiply the first and last terms:
24x^2
So find two numbers that multiply to 24x^2 and add to 11x.
This would be 3x and 8x
Rewrite the problem as
4x^2+3x+8x+6
Take the first and 3rd and 2nd and 4th terms
4x^2 and 8x
and
3x and 6
Factor by grouping
Take out a 4x for the first group to get 4x(x+2)
Take out a 3 for the 2nd group to get 3(x+2)
Rewrite as (4x+3)(x+2)
Hope this helps.

Answer:
support: 25%*100 > 10%*50
refute: 25%*50 < 10%*200
Step-by-step explanation:
0.25*100=25 > 0.10*50=5
0.25*50=12.5 < 0.10*200=20
Answer:
t = 2.5 s
Step-by-step explanation:
Suppose you have a water-balloon launcher. The balloon is 3 ft high when it leaves the launcher. Its equation is :
The above equation is a quadratic equation. The general equation is :
Here, a = 16, b = 38.8 and c = 3
The solution of quadratic equation is given by :
So, at t = 2.5 s the balloon is in air.
