Question

what is the answer??​

Answer 1

Answer:

$\frac{1}{x + 4} - \frac{1}{x - 7} = \frac{11}{30} \\ \frac{x - 7 - (x + 4)}{(x + 4)(x - 7) } = \frac{11}{30} \\ \frac{x - 7 - x - 4}{x {}^{2} - 7x + 4x - 28 } = \frac{11}{30} \\ \frac{ - 11}{x {}^{2} - 3x - 28} = \frac{11}{30} \\ (x {}^{2} - 3x - 28) (11) = 30 \times - 11 \\ x {}^{2} - 3x - 28 = - 30 \\ x {?}^{2} - 3x - 28 + 30 = 0\\ x {}^{2} - 3x + 2 = 0 \\ x {}^{2} - 2x - x + 2 = 0 \\ x(x - 2) - 1(x - 2) = 0 \\ (x - 1)( x - 2) = 0 \\ x = 1 \: or \: x = 2$
