49w² -112w + 64
first, you have to find 2 numbers that add up to equal -112, but also multiply together to get a product of 3136 (49 * 64)
two numbers that add to -112 and multiply to equal 3136 is -56 and -56
we can add them into the equation by putting them in for -112x
49w²-56w-56w+64
we now look at what the first 2 numbers have in common and what the last two numbers have in common
49w² and -56w both have w and 7 in common so we can divide 7w
7w(7w -8)
-56w and 64 both have -8 in common so we can divide by -8
-8(7w-8)
now we take the 2 numbers on the outside and bring down the numbers in the brackets
(7w-8)(7w-8)
(7w-8)²

Answer:
238
Step-by-step explanation:
Start with Raven's ants since hers is the one that everyone else's is based off of.
Raven = 208
Haley has half of that plus 76, so
Haley = (208/2) + 76
Haley = 180
If Haley's farm doubles in population, she would have 360 ants. That number is equal to Nate's number + 122. We have an equation of sorts there to solve for Nate's ants:
180(2) = N + 122 so
360 = N + 122 and
N = 238
Nate has 238 ants in his farm.
