How do you prove (a + b)^2 = a^2 +2ab + b^2

hint: (a + b)2 = (a + b)(a + b) may be a good way to get started. you can then do more algebra steps to the (a + b)(a + b) expression to eventually re-write it as a2 + 2ab + b2 .

why not give a simple counter example? if a=[0010] and b=[0001], then (a+b)2=[0011]2=[0011], – nex sep 3 '16 at 19: 30

but a2+2ab+b2=[0010]2+2[0010][0001]+[0001]2=[]+2[0010]+[0001]=[0021]

55/i dont know i do it for the points

step-by-step explanation:

answer: answer is c!

ok i got to organize the

3/15 and 12/55

3*

aha

3*4 equals 12 but not

a: no

b:

8/24 12/35

no

gautie

it's c

5/18 = 25/90

5*5=25

18*5 = 90

hope that you!

one more happy customer!
