Question

please solve this sum

Answer 1

$x = 4 \\ x = \frac{9}{ 2}$

Answer 2

Thus so

______________________________________________________________



. ====. x + 3 / x + 2 - ( 1 - x ) / x =. 17 / x

. ( x + 3 ) ( x ) - ( x + 2 ) ( 1 - x ) / ( x + 2 ) ( x ) = 17 / x

. x ² + 3 x - ( x - x² + 2 - 2x ) / x² + 2x = 17 / x

. x² + 3x - x + x² - 2 + 2x / x² + 2x = 17 / x

. 2x² + 4x - 2 ) ( x ) = 17x² + 34 x

. 2x³ + 4x²-2 x = 17 x² + 34x

. 2x³ - 13x²- 36 x = 0

By dividing by x to lhs rhs

. 2x²-13x-36 = 0

. then

. by d = b² - 4ac

. 169 + 288

. 457

the roots are

. -b + root d / 2a

. 13 + root 457 / 4 〰

. -b - root d / 2a

. 13 - root 457 / 4 〰
