The Theorem is a^2 + b^2 = c^2 Where a and b are sides of the right triangle and c is the hypotenuse of the right triangle.

Ok. Let a = x and b = x+7 therefore, (x)^2 + (x+7)^2 = (8+x)^2

Expand the terms for both sides of the question, then simplify it. As Yahoo! mentioned, you can expand the term (a+b)^2 by using the identity (a+b)^2 = a^2 + 2ab + b^2. If you don't know where this identity comes from, you can simply perform multiplication for the term, i.e. (a+b)^2 = (a+b)(a+b), now expand it. What have you got for now?

That is not Pyth. Thm. It's just simple multiplication of some factors. For instance, \[x^2 = x \times x\]\[x^3 = x \times x \times x\] Similarly, \[(a+b)^2 = (a+b) \times (a+b)\]It can be expanded in this way: \[(a+b)^2 = (a+b) \times (a+b) = a(a+b) + b(a+b)\]Can you further expand and simplify it?

\sqrt{x} = \(\sqrt{x}\) and so on.. You can try these on the equation button. Though, back to your question, are you still having trouble with your question?

andriod09 Group TitleBest ResponseYou've already chosen the best response.0
yes. and i see the \sqrt{x} = \(\sqrt{x}\) like i see all the braces, the terms for them, and everything like that. my mathjax thing isn't working atm

is it: b(a+b)=b(a)+b(b)=b^2+ba?

Yes! Now combine them What is a(a+b) + b(a+b) ?
