Question

4x2 + 4x + 1 = (2x + 1)2

Answer 1

true of false

Answer 2

Is it : \[\large{4x^2 + 4x + 1 = (2x+1)^2}\] or \[\large{4x^2 + 4x + 1 = (2x+1)2}\] ?

Answer 3

the 1st one

Answer 4

OK so do you know the formula for \(\large{(a+b)^2}\) ?

Answer 5

i think so

Answer 6

What is it ?

Answer 7

ummmm

Answer 8

this is hard

Answer 9

Thanks a lot Mertsj

Answer 10

yw

Answer 11

(a+b)^2 = a^2+2ab+b^2

Answer 12

We suspect our trinomial is of this form since the first term is a perfect square and the last term is a perfect square.

Answer 13

So then we think: if 4x^2 is a squared, then a is 2x. If b^2 is 1 then b is 1 and 2ab is 2(2x)(1) which is the middle term.

Answer 14

So we know we have a trinomial square and the factors are (2x+1)^2
