how to form QUADRATIC EQUATION from roots.

Hello everyone, greetings of the season. As we are asked to do or to formulate a quadratic A quadratic equation whose roots are -10 and 2 means that the equation can be written as (x + 10)(x - 2) = 0. Expanding this, we get x² + 8x - 20 = 0. This is the quadratic equation with roots -10 and 2. That's the solution or the answer to the roots; I was minus 10 and 2, so we are asked to form the quadratic equation now then this is a very simple question because you are just going to apply a The method I'm about to give you is going to be the simplest method you'll ever use. To solve something like this, now let's get to it. We're given something like this—all you need to do is to subtract each root from x, subtract each root from x, multiply whatever you got Simplify: see me do it now. So we are going to subtract each root from x, so we already have x. so minus minus 10 because we have minus 10 here, okay, bracket closes, we open another bracket and we are subtracting the root, which is 2, from x, that is x minus 2, and we are equating everything to be equal to zero, you see what I told you is a very easy thing. Now, what do we do? We are Not working on this, okay. Now how do we go about that? We have that x minus minus 10 is going to give us what x plus 10 why because minus times minus is equal to us plus so x minus minus 10 will give us x plus 10, okay? Into what x minus 2 is equal to zero, okay? Let us continue; we are not We're going to open these brackets; well, we're going to open these brackets. But if you've followed me this far, it means you actually love what I'm doing, okay? and if you want more of this and you want to see more of these things, then please click on that subscription button, subscribe to the channel, and also turn on your notification bell so that you a video now let us go ahead and expand this and get the solution we are going to have x times x see how we are going to expand it: this x, we multiply this one, this x again, is going to Multiply by minus two, then we are done with x; that means this x will go into the two of them. We are through with it. We also go in with 10 to the two of them, that is 10. We multiply x. then we also multiply what minus 2 times x, I'll do it: x times x is going to give you what, x squared x times minus 2, okay, we give you minus 2x; we are through with x, we are going in with plus 10. plus 10 times x gives you plus 10x, okay; plus 10 times minus 2 gives you minus 20 remember that plus times minus gives you minus, okay? So plus 10 times minus 2, whenever I See it this way: whenever someone who is good always associates with someone who is not good, okay. They say that's a bad character's voice, good morale, something along those lines, so when plus goes to negative Now this is equal to zero, so we have x squared minus 2x plus 10x, which is going to give Tell me what c minus 2 plus 10 is—it's certain as if I should write plus 10 first, plus 10, and I write minus 2, so it's something as 10 minus 2 is going to give us what, 8, so it's going to give us plus 8x plus 8x minus 20 equals zero, so this is your final answer. This is the quadratic equation, you are looking for; have a lovely day and bye
