Okay, So we asked the fact that our fallen So we'll fact the regular ping, you have a which is equal just ever you, which is to go to 33 see which is equal to make it a 10. So our key number is equal to a temp. See, which is seven times they go 10. Thank you. Me? Negative. 70. So we need the product, the two numbers to be equal to our key number. And those numbers sound need to be equal to be, which is 33. Okay, so two numbers whose products are 70 is a seven and 10 but mm. If we do seven plus 10 we get 17 not 33. So let's try to other numbers. So we can try 35 times two. That gives a 70. And then, if we some these two, we get 37. But if we have negative to instead of positive, too with your 33 then 35 times negative to gives me negative 70 So we'll split our middle turn into it's seen negative, actually. Let's do 35 x minus two x. Okay. And now I'll factor my 1st 2 times we can fact out of X and a seven. So we're left with X Plus wife. And for our last two terms, we can fact out, and I get to have X plus five times native to okay. And now we have exposed five in common. So a factor that out. So I get experts. Five time seven X minus two
