ln(4x - 5) + (a million/2)ln(9) = 2ln(x + a million) ln(4x - 5) + ln(9^(a million/2)) = ln[(x + a million)^2] ln(4x - 5) + ln(3) = ln(x^2 + 2x + a million) ln[3(4x - 5)] = ln(x^2 + 2x + a million) ln(12x - 15) = ln(x^2 + 2x + a million) 12x - 15 = x^2 + 2x + a million 0 = x^2 - 10x + 16 0 = (x - 8)(x - 2) x - 8 = 0 or x - 2 = 0 x = 8 or x = 2 <===answer
