Question

(a + b)2 = a2 + b2

If the statement is false, give a counterexample.
____________________________________________

A) False; (2 + 0)2 = 4
B) False; (1 + 2)2 = 9
C) False; (0 + 1)2 = 1
D) The statement is true.

Answer 1

Well I know it's false, but I'm pretty sure all the ones with false are right.. ?!

Answer 2

lol do it like the question

A. (2 + 0) ^2 = 2^2 + 0^2 = 4
B. (1 + 2)^2 = 1^2 + 2^2 = 9
C. (0 + 1)^2 = 0^2 + 1^2 = 1

remember you are looking for double false

Answer 3

Double false..?!

Answer 4

your objective is to prove (a+b)^2 = a^2 + b^2 WRONG

Answer 5

Mhmm.

Answer 6

by double false i meant that \((a+b)^2 \ne a^2 + b^2\)

Answer 7

it's double false because it has a FALSE at the beginning as well...dont mind it...that was supposed to be a pun

Answer 8

Oh! Okay. But I solved them, I mean 2+0 = 2. 2^2= 4 . So that can't be right. A isn't right. Right?

Answer 9

uhmmm if you mean A isnt the answer then yes

Answer 10

Okay yeah I meant that. XD.
1+2= 3. 3^2= 9. So its not B either.

Answer 11

0+1= 1. 1^2 = 1. So its not C. I clicked D but they said it was wrong. So now I'm like. Confused.

Answer 12

i think you are confused...look at what i did

(1 + 2)^2 = !^2 + 2^2

Answer 13

Oh............ Heh. okay nvm...... Lol. XD

Answer 14

It's B!

Answer 15

Answer 16
