2a
2a + 11a - 5a = 8a
5a = -5a + 5Add 5a to each side:10a = 5Divide each side by 10:a = 5/10 = 1/2
The square root of 25a squared is 5a. The square root of 16 is 4.So the answer is (5a+4)(5a-4)
7a+10=2a 7a+10-2a=0 5a+10=0 5a=-10 a=-2

2a-5
2a + 11a - 5a = 8a
2a+5
5a = -5a + 5Add 5a to each side:10a = 5Divide each side by 10:a = 5/10 = 1/2
5a
It simplifies to 5a+4 !
The square root of 25a squared is 5a. The square root of 16 is 4.So the answer is (5a+4)(5a-4)
2a + 10 + 5a - 2 = (2a + 5a) + (10 - 2) = 7a + 8
25a2 - 80a + 64
(5a+8) - (2a+4) =3a +4 To do this, simply subtract like terms. 5a-2a=3a and 8-4=4
