Step-by-step explanation:
*************************************************************************************
~ We know root of any equation = (-b + √D)/2a or (-b - √D)/2a
~ hence as given in the above question...
>>>>BY TAKING L.C.M :
(x+3)(2x-3) - (3x-7)(x+2) =0
=> (2x^2 ) -3x +6x -9 - { (3x^2) +6x -7x -14} =0
=> (-x^2) + 4x +5 =0
IN THIS EQUATION : (b = 4); (a=-1);(c=5)...................(2.)
D(discriminant)= 16 -4(-1)(5)
=> 16 + 20 =>36
so, {√D = 6}...................(1.)
FROM 1 AND 2 EQUATION PUT VALUES IN FORMULA:
x = (-4 + 6)/2(-1) => ( -1) ans...
OR
x = (-4-6)/(-2) => (5) ans......
