since a=1a, 3a-1a=2a

(2a - b)(2a + b)

-16A

2a+6b

6a to the second power minus 8ab + 2a

(a - 2b)(2a - b)

It is: 2(a-2)

2a + 11a - 5a = 8a

-2a - 4 = -16.8 -2a = -12.8 a = -12.8/-2 a = 6.4

(2a - 5). Take the value of a. Double it to get 2a Take away (subtract 5) to get 2a - 5

2(a + 7)(a - 6)

x equals negative b plus or minus the square root of b squared minus 4bc over 2a

(5a+8) - (2a+4) =3a +4 To do this, simply subtract like terms. 5a-2a=3a and 8-4=4

Pull out the GCF 4(2a - 1)

When simplified it is: 2a+8b+4

It is [(2a+2h+5) - (2a+5)]/h = 2h/h = 2

2a -3 means 2 times a minus 3 if a = 2 we have 2 x 2 - 3 = 4 - 3 = 1

The quadric equation is: negative b plus or minus the square root of b squared minus 4ac all over(divided by) 2a

6a2 - 8ab + 2aas you can see a is common to all terms. And 2 is a factor of 6,8, and 2. So 2a is a factor of all three terms:2a(3a-4b+1)

midpoint: (x1+x2/2 , y1+y2/2) quadratic: -b plus or minus square root b squared minus 4ac divided by 2a
