Your expression is this... x2 + y2/x
(a - 2b)(2a - b)
1. Anything divided by itself always equals 1.
2a2 x 3a-3 = (2 x 3)a(2 + -3) = 6a-1
No
a/2a^2 You can take "a" out of both of those. It leaves you with 1/2a
-b + or - the square root of b squared - 4ac over/divided by 2a
22
4aa-bb fits the special type of polynomial in the form of x**2-y**2 which can be rewritten as (x-y)(x+y) sqrt(4aa) = 2a sqrt(bb) = b (2a-b)(2a+b)
x2 divided by x would simply be x.
x-1
(2a + b)(a + 3b)
Your expression is this... x2 + y2/x
x2/(-x) = -x.
(a - 2b)(2a - b)
1. Anything divided by itself always equals 1.
X2 (X squared)
