Factor 2a squared plus 3a plus 1?
(2a+1)(a+1)
What is 5a plus 3 plus 2a-2 plus a?
5a + 3 + (2a - 2) + a= 5a + 3 + 2a - 2 + a= 8a + 1
How do you solve -2a plus 5 equals 1?
-2a + 5 = 1 -2a = -5 + 1 -2a = -4 a = -4/-2 a = 2
How do you simplify this expression 12a - 6a plus a?
12a- 6a + a = 7a Since they all have the same variable, you can simply add and subtract 12-6 = 6 6+1 = 7

2a-3+4b-2a-b-2a-b-3+5 Can be simplified to: 3b-1
What is five times the sum of some number plus 3 is equal to 7 times the number minus 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
How do you simplify open parenthesis A2 plus 7A-8close parenthesis divided by open parenthesis A2 plus 6A-7close parenthesis?

a/2a^2 You can take "a" out of both of those. It leaves you with 1/2a
Describe a symbolic method for solving a linear equation?
i dont understand what you mean by symbolic but ill just do an example 2a + 3 = 4 - 5a first collect like terms 2a +3 -3 = 4 -3 -5a 2a = 4-3 - 5a 2a + 5a = 1 - 5a + 5a 2a + 5a = 1 7a = 1 divide both sides by the coefficient of the unknwown(i.e. the number in front of the letter) 7a/7 = 1/7 a = 1/7
