Answer 2

$(x + 6)(x - 6) - (x - 5) {}^{2} = 40 - 17 \\ (x - 2) \\ {x}^{2} - {6}^{2} - ( {x}^{2} + {5}^{2} - 2 \times 5 \times x) = 40 \\ - 17( {x} - 2) \\ {x}^{2} - 36 - ( {x}^{2} + 25 - 10x) = 40 - 17 \\ (x - 2) \\ {x}^{2} - 61-{x}^{2}+10x = 40 -17x +74 \\ - 61 + 10x = -17x + 74 \\ - 61 - 74 = -17x - 10x \\ - 135 = -27x \\ x = \frac{-135}{-27} \\ x = 5$
