Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

-1     OR     5

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......
