hello guys today we like I mentioned we were talking about the Pythagorean theorem here is your such a question how can you prove the factor theorem or maybe we should just change it to how can you use the Pythagorean theorem and then I will show you how the answers  it's a huge warm out of I will show you three and four in class because I did not give myself enough space to write out all of the work here especially with these styluses that are very inaccurate accurate so but I will say the answers to one or two but posit right now work what is your partner make sure you guys get the right answers or at least the same answers and then the next part you'll see is me  just giving you the answers so here's the answer to number 1 x equals 5 nice and easy however for the second one we x equals square root for 56 and since I'm not there to answer any questions that you might have had on your homework I figured I would go ahead and simplify that route covert for you or with you guys plan x equals  square root for 56 did it the math and that's 12 + 38 multiplies to 12/6 and 2 multiply to 6 and 238 is 2 and 19 and then I thought we can do so we have a 3 we have a 2 we have another 2 and another 2 and the 19 so do I have any pairs answers yes I have a pair of twos so to comes outside everything that's left those on the inside 6 * 2 I'm sorry 3 * 2 is 6 + 6 * what team that part I didn't do yet is $114 to Rand  114 equals so this right here is your final answer and then like I said we'll do three and four together in class tomorrow don't worry about that if someone in first. Could remind me of that and someone at 6. Remind me that we need to finish that that would be super great turn on for today  play the sad Pythagorean theorem on the line that says Pythagorean theorem if you could write c squared equals a squared what's B squared  the other ways also true or you can put  a squared plus b squared equals c squared whatever makes your heart happier is fine just remember that c and I don't know if you want to make this note somewhere what sea is always the longest time in parenthesis that's the Fanny deposit to finish writing things down that's fine oh wait no I didn't even talk about the bottom part alright search playing in theorem and we also have things called Pythagorean triples that gives you is a set of three positive integers a b and c that satisfy the equation in other words you get you use all whole numbers whole numbers so that means no decimals no fractions no anything these are some examples website  these are some examples down here below common Pythagorean triple in some of their multiples 345 will come up a lot that's when I suggest you memorize also if you multiply three four five what is the make it 6 8 10 that's a common triple 5 13 12  815-1772 25 those are all Pythagorean triples because those no none of those numbers have any fractions or decimals but they still make the Pythagorean theorem true so when a question asks does it make Pythagorean triple you ask are they all whole numbers let's look at a couple examples but I'm going to go ahead and stop this video and you can open up the next one
