Equation: p=√(-x^2+100) Step One: We know that p = $6, so the first step will be to place 6 in place of ‘p’. 6 =√(-x^2+100) Step Two: The next step, will be to get rid of the square root. So, to get rid of the square root we must square it. Remember with equations, what you do to one side you do it to the other. 〖(6)〗^2 =(√(-x^2+100) )^2 Once we squared both sides the square root will cancel each other out, and the 6^2 will then become 36. 〖(6)〗^2 =(√(-x^2+100) )^2 36 =-x^2+100 Step Three: The next step will involve getting the variable by itself, in this case ‘x’ is the variable. So, to get ‘x’ by its self we must subtract 100 from both sides. 36 =-x^2+100 -100 -100 So, 36-100 equals -64, and the 100s will cancel each
