That factors to (a + 1)(a + b)
a = -1, -b
b = -a
The square root of 149 (7 squared plus 10 squared equals 149).
(a + x^2)(b + y^2)
b2 + ab - 2 - 2b2 + 2ab = -b2 + ab - 2 which cannot be simplified further.

Commutativity.
A = 1, B = 9
to solve ab=c+a for a:Divide both sides by b, so:a= (c+a)/b
The square root of 149 (7 squared plus 10 squared equals 149).
yes because ab plus bc is ac
(a + x^2)(b + y^2)
b2 + ab - 2 - 2b2 + 2ab = -b2 + ab - 2 which cannot be simplified further.

Commutativity.
The existence of the additive inverse (of ab).
3y=ab. Divide by 3 to get y=ab/3
x2y + axy + abx + a2b Factor by grouping. xy(x + a) + ab(x + a) (xy + ab)(x + a)
associative property
