Part A: Factor 3x2y2 − xy2 − 2y2. Show your work. (4 points)
3x^2y^2 − xy^2 − 2y^2
y^2 ( 3x^2 - x -2 )
y^2 (3x+2)( x - 1)
Part B: Factor x^2 + 6x + 9. Show your work. (3 points)
x^2 + 6x + 9
= x^2 + 2*3x + 3^2
= (x+3)(x+3)
= (x+3)^2
Part C: Factor x2 − 25. Show your work. (3 points)
x^2 - 5^2

Answer:
4.66
Step-by-step explanation:
Cause 4 would be 4.0 and then you take 100 and divide by the denominator and you get .33 for every 1/3. Since you have 2/3 it would be .66, then your answer would be 4.66
Y=55
Explanation:
If you’re looking to see how 11 and y would match -9 and -45 you would find the unit rate of -9 and -45.
-9/-9=1
-45/-9=5
So if the y is going up by 5’s it would be 55.
1. 25 + 3u = 2u
-3u = -3u
25 = -u
-25=u
2. 14x - 8 = 6x
8x - 8 = 0
8x = 8
x=1
3. 8.5 - 3z = -8z
8.5 = -5z
-1.7 = z
4. 9m + 14 = 2m
7m + 14 = 0
7m = -14
m = -2
