Given:
[tex] \\ \frac{1}{x +3 } + \frac{1}{x} = \frac{1}{2} \\ [/tex]
[tex] \\ \sf{ \small{(x)(2)1 + (x + 3)(2)1= (x + 3)(x)1}} \\ [/tex]
[tex] \\ \sf{2x + 2x + 6 = x {}^{2} + 3x}\\ [/tex]
[tex] \\ \sf{4x + 6 = {x}^{2} + 3x }\\ [/tex]
[tex] \\ \sf{4 x + 6 - {x}^{2} - 3x = 0} \\ [/tex]
STANDARD FORM:
[tex] \\ \sf{ - x {}^{2} + x + 6 = 0} \\ [/tex]
