Yeah, the equation three minus the square root of why is equal to one. That's first. Let's move all our constance toe one side of the equation. Let's go ahead and subtract three. Let's subtract three from both sides so we'll just leave on minus three for minus 30 So zero minus squared of why that's minus the square root of why is equal to a one minus three. What? One minus three is negative. Two. Okay, Now to sell for Why wasn't I have negative? Describe it of why I can go ahead. I can divide or multiply both sides by a negative one to just basically change the signs. So I want to buy my negative one. Um right. Everything here I get that square root off. Why is equal to a positive two? And then it wasn't have a square root of why I can go ahead and square both sides because the square root of why squared is equal toe. Why so, therefore, why is equal to two squared or two times two, which is for so once again. Here we see that Why is he could before meaning our solution set is set containing just the number for all right. Take care
