Because of the way this is written, there are two possibilities in simplifying. Choose the one that applies:
Four times 3^2 minus two = 34.

Let y= ab+(- a)(b) +(-a)(-b) factor out -a y= ab+(-a){b+(-b)} y=ab+(-a)(0) y =ab -------------------(1) now factor out b y= b{a+(-a)}+(-a)(-b) y= b(0) +(-a)(-b) y= (-a)(-b)-----------------(2) equate (1) and (2) (-a)(-b)=ab minus x minus = positive
b2 + ab - 2 - 2b2 + 2ab = -b2 + ab - 2 which cannot be simplified further.
16 - 2 = 14
Two negatives make a positive so your equation simplifies firstly as 4ab + 3ab and finally as 7ab.
Four times 3^2 minus two = 34.
5 to the power of 2

b2 + ab - 2 - 2b2 + 2ab = -b2 + ab - 2 which cannot be simplified further.
16 - 2 = 14
Four times minus six is minus twenty four.

C minus B equals AB
No, AB+ people can receive blood from all blood groups.
(b-c)(a+b)-ac
