Question and answer
Perform the indicated operation. (25m 2 - 20m + 4) ÷ (5m - 2) 2m- 5 5m- 2 5m+ 2
(25m^2 - 20m + 4) ÷ (5m - 2) = [(5m - 2)(5m - 2)]/(5m - 2) = 5m - 2

1 Answer/Comment
(w^3 + 64) ÷ (4 + w) = [(w^2 - 4w + 16)(w + 4)]/(w + 4) = w^2 - 4w + 16

x - y = 4
x + y = 8
adding up equations the result is: 2x = 12, x = 6.
x - y = 4 x + y = 8 The x-coordinate of the solution to the system shown is 6.

7x - 3y = 4 multiple 4 on both sides the result is:
28x - 12y = 16 (equation 1)
2x - 4y = 1 multiple -3 on both sides the result is:
-6x + 12y = -3 (equation 2)
adding up equation 1 and 2 the result is:
22x = 13
x = 13/22
7(13/22) - 3y = 4
91/22 - 3y = 4
-3y = 4 - 91/22 = 88/22 - 91/22 = -3/22
y = (-3/22)/(-3) = 1/22
The solution for the system 7x - 3y = 4 2x - 4y = 1 is (13/22, 1/22)
