1 over (3 times the square root of 6)
The factorization of 5a^2 + 24a - 5 is (5a - 1)(a + 5).
5a - 1 = a - 7 4a = -6 a = -1.5
5a + 3 + (2a - 2) + a= 5a + 3 + 2a - 2 + a= 8a + 1

5a + 3 = 7a - 1 add 1 to both sides 5a + 4 = 7a so 4 = 2a as 5a + 2a = 7a 4 = 2a = 2 x 2 so a = 2 Check: then 5a + 3 = 10 + 3 = 13 and 7a - 1 = 14 - 1 = 13
6b-5a = 1
Answer to: 5a + 1 = a - 3a = -1
(a2 + 2a + 1)/(5a + 5)factor, top and bottom(a + 1)(a + 1)/5(a + 1)cancel an (a + 1) top and bottom= (a + 1)/5=========

5a(2b + 1)
5a = -5a + 5Add 5a to each side:10a = 5Divide each side by 10:a = 5/10 = 1/2
If: 5a-1+a = 11 Then: a = 2
5a^2 - 5a - 60 ---- 5(a2 + a - 12)
