प्रश्न

`3((3x-1)/(2x+3))-2((2x+3)/(3x-1))=5,x≠1/3,-3/2` 

उत्तर

`3((3x-1)/(2x+3))-2((2x+3)/(3x-1))=5,x≠1/3,-3/2`  

⇒`(3(3x-1)^2-2(2x+3)^2)/((2x+3)(3x-1))=5` 

⇒`(3(9x^2-6x+1)-2(4x^2+12x+9))/(6x^2+7x-3)=5` 

⇒`(27x^2-18x+3-8x^2-24x-18)/(6x^2+7x-3)=5` 

⇒`(19x^2-42x-15)/(6x^2+7x-3)=5` 

⇒`19x^2-42x-15=30x^2+35x-15` 

⇒`11x^2+77x=0` 

⇒`11x(x+7)=0 ` 

⇒`x=0  or  x+7=0` 

⇒ `x=0  or  x=-7 ` 

Hence, 0 and -7 are the roots of the given equation.
