Answer 2

Well remember

\[\large (2\sqrt{5} + 3\sqrt{7})^2 = (2\sqrt{5} +3\sqrt{7})(2\sqrt{5} + 3\sqrt{7})\]

Then you distribute it out using the foil method

Answer 3

\[(2\sqrt{5} + 3\sqrt{7}) (2\sqrt{5} +3\sqrt{7})\]

Answer 4

ok so how do i use foil?

Answer 5

or whats my next step?

Answer 6

So foil basically says...

You take the first term in the first parenthesis, and multiply it by the first term in the second parenthesis

Then the first term in the first parenthesis times the 2nd term in the 2nd parenthesis

Following that we take the 2nd term in the first parenthesis, times the first term in the second parenthesis

and finally the second term in the first parenthesis, times the 2nd term in the second parenthesis

Or more easily, First, Outside, Inside, Last
