Answer:
2a + 5b - 5
Step-by-step explanation:
4a^2 + 25b^2 + 20ab - 10a - 25b
(2a)^2 + (5b)^2 + 20ab - 5(2a + 5b)
(2a)^2 + (5b)^2 + 2*2a*5b - 5(2a + 5b)
(2a + 5b)^2 - 5(2a + 5b)
(2a + 5b) (2a + 5b) - 5(2a + 5b) = 0
(2a + 5b) (2a + 5b) = + 5(2a + 5b)
(2a + 5b) = 5(2a + 5b)/(2a + 5b)
(2a + 5b) = 5
2a + 5b - 5
