2a*3 = 8+4a 6a = 8+4a 6a-4a = 8 2a = 8 a = 4
Solve the following equation for A : 2A/3 = 8 + 4A
= 2a - 10
a=8 -5+4x8=27
1/2
a3 - 2a2 + 4a - 8 = a2(a - 2) + 4(a - 2) = (a - 2)(a2 + 4)
First you can factor a^2 from the first two terms and 4 from the last two terms. (a^2)(a-2)+4(a-2) You can see that they both have (a-2) as a factor. So it is (a^2+4)(a-2)
The greatest common factor (GCF) is 4.
2a2+33a+136 = (2a+17)(a+8) when factored
8
2a*3 = 8+4a 6a = 8+4a 6a-4a = 8 2a = 8 a = 4
32a + 8= 8(4a+1)
6a - 8 - 4a - 2 → 6a - 4a - 8 - 2 → 2a - 10
a = -2-4a/3-2 = 8-4a = 8(3-2) times both sides by (3-2)-4a = 24-16-4a = 8-a = 2 divide both sides by 4a = -2 times both sides by -1
8
−4a + 139 = 4a + 123 → −8a = −16 → a = 24a + 123 → 4(2) + 123 = 8 + 123 = 131°
5a - 10 = 4a + 8 is a linear equation in one variable.
