a2 - 13a + 30 = a2 + 4a + 4 a - 10 a + 2 => (a2 - 13a + 30)(a + 2) = (a2 + 4a + 4)(a - 10) => a3 + 2a2 - 13a2 - 26a + 30a + 60 = a3 - 10a2 +4a2 + 4a - 40 => - 11a2 + 4a + 60 = - 6a2+ 4a - 40 => - 11a2 + 6a2 + 60 + 40 = 0 => - 5a2 + 100 = 0 => 5a2 = 100 => a2 = 20 => a = √20 Insert the value of'a'and you will get the answer.
