Question

is this answer correct?
problem: Find the product: (x-6y)(x+6y)

my answer is: x^3-4x^2+6x-24=0

Answer 1

no:/

Answer 2

can you please show me how to get it then?

Answer 3

No the correct answer is x^2 - 36y^2
Just apply the formula of (a-b)(a+b)=a^2- b^2

Answer 4

gee i was way off then can i show you another one to see if it is right?

Answer 5

problem : (4X+4Y)^2
answer : 16x^2+32xy+16y^2

Answer 6

Use the difference of two squares formula:\[(\color{red} a+\color{red} b)(\color{blue}a-\color{blue}b)=\color{red} a\color{blue}a+\cancel{\color{red} a\color{blue}b}-\cancel{\color{red} a\color{blue}b}+\color{red} b\color{blue}b=a^2-b^2\]

Answer 7

ya:)
\[\LARGE{\color{red}{(a+b)(a-b)=a^2-b^2.}}\]So; \[(x-6y)(x+6y)=(x^2)-(36y^2)=x^2-36y^2.\]\[\color{green}{\text{It is ur answer.}}\]

Answer 8

Use the difference of two squares formula:\[(\color{red} a+\color{red} b)(\color{blue}a-\color{blue}b)=\color{red} a\color{blue}a+\cancel{\color{red} a\color{blue}b}-\cancel{\color{red} a\color{blue}b}+\color{red} b\color{blue}b=a^2-b^2\]

Answer 9

nope...(x-6y)(x+6y)
foiled correctly it would be
x^2-36y^2

Answer 10

gt it?

Answer 11

i was off on that one too. I will go back and re read thank you

Answer 12

k! yw ^_^
