Solve x2 + 8 = x + 72. cccc eeeeA. eno solution B. e 64718C. e64718D. e72 ee
B
Step 1: x2 + 8 = (x + 72)
Step 2: (x2 + 8)^{2} = (x + 72)^{2}[Square each side of the equation.]
Step 3: x^{2} + 8 = x^{2} + 144x + 5184[(a + b)^{2} = a^{2} + 2ab + b^{2}.]
Step 4: 0 = 144x + 5176
Step 5:  5176 = 144x
Step 6:  647 = 18x
Step 7:  64718 = x
Step 8: The solution is  64718.
