6a - 8 - 4a - 2 → 6a - 4a - 8 - 2 → 2a - 10
4a - 5a^2
To simplify the expression (4a + 3(a^2)), you first distribute the (3) to (a^2), resulting in (4a + 3a^2). The expression cannot be simplified further since it consists of terms of different degrees. Therefore, the simplified form is (3a^2 + 4a).
−4a + 139 = 4a + 123 → −8a = −16 → a = 24a + 123 → 4(2) + 123 = 8 + 123 = 131°

(4a)2 or 16a2
4a-2 = 2
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
4a-2c = 2
6a - 8 - 4a - 2 → 6a - 4a - 8 - 2 → 2a - 10
There are two answers in the solution set. To solve this we factor the left side to become 4a(a-4). This lets us get the 4. The other answers is 0. Set 4a=0 and solve for "a" and then a-4=0 and solve for "a."
4a^2 - 5a^2 = -a^2
5a or 4a squared

4a + 2 = 4(6) + 2 = 24 + 2 = 26
