00:01 In this question we are asked to solve this is radical equation.
00:04 So let's start to solve this problem.
00:06 Here from the given equation we obtain square root of x plus 3 is equal to x minus 3.
00:14 Now after taking a square in both sides we obtain x plus 3 equals to x minus 3 square.
00:23 Now from this we obtain x plus 3 equals to square of x minus 3 becomes equal to x squared minus 6x plus 9.
00:36 Now after simplifying this, we obtain x square minus 6x plus 9 minus x minus 3 equals to 0.
00:46 Now from this we obtain x squared negative 6x and negative x becomes equal to negative 7x.
00:53 9 minus 3 becomes equal to 6 equals to 0.
00:57 Now from this we obtain x square i can write negative 7 x is equal to negative 6 x minus x plus x plus 6 equals to 0...
