Best Answer

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.

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)

2ab

b2 + ab - 2 - 2b2 + 2ab = -b2 + ab - 2 which cannot be simplified further.

(a+b)(a squared-ab+b squared)

No. A times B = AB

The existence of the additive inverse (of ab).
