That factors to (a + 1)(a + b) a = -1, -b b = -a
A = 1, B = 9
(a3 + b3)/(a + b) = (a + b)*(a2 - ab + b2)/(a + b) = (a2 - ab + b2)
to solve ab=c+a for a:Divide both sides by b, so:a= (c+a)/b
No. A times B = AB
Plus ab is an algebraic expression. As given you cannot solve it. However, If you have x +ab = c Then 'ab' can be solved. We do this by subtracting 'x' from both sides. (Preserve equality) x - x + ab = c - x x-x = 0 , just like 2 - 2 = 0 Hence ab = c -x
No, A+B is left as A+B AB would be A x B
For a baby with AB blood type : both parents should be AB. or one is AB and the other is B. or one is A and the other is B.
This expression can be factored. ab + 3a + b2 + 3b = a(b + 3) + b(b + 3) = (a + b)(b + 3)
yes, because the offspring could take AB or just B or even BB .
(a + b)(b + c)
a(b+3)+b(b+3)
