Question

Use the “difference of squares” rule to factor the following expression: 9x^2 – 49y^2

Answer 1

This expression can also be written as:

\[(3x)^2 - (7y)^2\]

And you should remember one thing:

\[a^2 - b^2 = (a +b)(a-b)\]

Use this formula to solve and get the answer...

Answer 2

9x^2-49y^2
(9x-49y)(9x+49y)

Answer 3

thanks

Answer 4

here a=9x,b=49y

Answer 5

If this question can be solved further then you can tell him the whole by doing solution on your own @nitz ..
