If your problem looks like this: 4a-a=_ the answer is... 3a

7a-2b

A = 6

3a - 2b

4a2 - 9a + 5 = 4a2 - 4a -5a + 5 = 4a(a - 1) - 5(a - 1) = (4a - 5)(a - 1)

2a+6b

4a+3-a =12 4a-a = 12-3 3a = 9 a = 3

4a + 3a = (4 + 3)a = 7a

a < -12

sqrt(4a2) = 21plus or minus (2a) = 21plus or minus (a) = 10.5a = +10.5a = -10.5

It is: (a+1)(a+3) when factored

It depends on the exact form. If it is 4a + 12/(a + 3) then a cannot be -3 However, (4a + 12)/(a + 3) simplifies to 4. So there is no variable to worry about!

2a*3 = 8+4a 6a = 8+4a 6a-4a = 8 2a = 8 a = 4

idont know

11a+9 = 4a+30 11a-4a = 30-9 7a = 21 Solution: a = 3

"a" plus "3a" is equal to 4a. (3a+a=4a). You already have 3 "a's" and then you add another "a."

A = 7. 4a + 3 - a = 24 4a - a = 21 3a = 21 a = 7

Zero

11a + 9 = 4a + 30Subtract 9 from both sides to get: 11a = 4a + 21Subtract 4a from both sides to get:7a = 21Divide both sides by 7 to get:a = 3And there's your answer: a = 3

Answer = 2 - (-3) = 2 + 3 = 5 minus minus means plus.

4a3 - 4a2 = 4a2*(a - 1)

Because adding a negative is the same as subtracting a positive. In other words, minus a plus is he same as plus a minus. For example 5+ (-3) = 5-3 = +2 5 -(+3) = 5-3 = +2 Remember minus a plus = = minus plus a minus = minus plus a plus = plus minus a minus = plus

It is a bigger plus. For example, 5 - (-3) = 5 + 3 = 8

It is -44 + 4a
