Errgent israel started to solve a radical equation in this way: β 4 = x β 4 + 4 = x + 4 = x + 4 ()2 = (x + 4)2 x + 6 = x2 + 8x + 16 x + 6 β 6 = x2 + 8x + 16 β 6 x = x2 + 8x + 10 x β x = x2 + 8x + 10 β x 0 = x2 + 7x + 10 0 = (x + 2)(x + 5) x + 2 = 0 x + 5 = 0 x + 2 β 2 = 0 β 2 x + 5 β 5 = 0 β 5 x = β2 x = β5 solutions = β2, β5 what error did israel make?
