Question

Choose the correct product of (6x + 2)2.

36x2 − 4

36x2 + 4

36x2 − 24x + 4

36x2 + 24x + 4

Answer 1

\(\huge(a+b)^2=a^2+2ab+b^2 \\ \text{just put a=6x and b=2, what u get ?}\)

Answer 2

how did you get that? These confuse me so much.. (6x+2)^2 = 6x^2 + 2(12) + b^2

Answer 3

a= 6x
a^2 = (6x)^2 = 6^2 x^2 = 36x^2
got this ?

Answer 4

aaaah, its just confussing....

Answer 5

which part ?

Answer 6

Here's an alternate route:

(6x + 2)^2

(6x + 2)(6x + 2)

6x*(6x + 2) + 2*(6x + 2)

Now distribute. Then combine like terms.
