Question

How do I solve this? What’s the answer? X=? X=?

Answer 1

`(1)/(2x - 3) + (1)/(4x + 9) = 7`

4x + 9 + 2x - 3 = 7(2x - 3)(4x + 9)

6x + 6 = 7(8x² + 6x - 27)

6x + 6 = 56x² + 42x - 189

56x² + 36x - 195 = 0

x = (-36 ± √(36² - 4(56)(-195)))/112

= (-36 ± √44,976)/112

= (-36 ± 4√2,811)/112

= (-9 ± √2,811)/28

= about -2.2, 1.6
