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
What is it you want to solve? You can factor it, taking out the common factor, "a". Thus, a + ab = a(1 + b). Or, if you want to convert it to a number, you can only do this if you know the values for "a" and "b". In this case, replace the values, and do the calculation.
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)
(a + b)(b + c)
yes, because the offspring could take AB or just B or even BB .
a(b+3)+b(b+3)
x2+bx+ax+ab = x2+ax+bx+ab = x(x+a)+b(x+a) = (x+a)(x+b)
