Question

6x^2+9x-8=0 factorize it​

Answer 1

Answer:

6x2-9x-8 = 0 by the Quadratic Formula .

 According to the Quadratic Formula,  x  , the solution for   Ax2+Bx+C  = 0  , where  A, B  and  C  are numbers, often called coefficients, is given by :

                                     

            - B  ±  √ B2-4AC

  x =   ————————

                      2A 

  In our case,  A   =     6

                      B   =    -9

                      C   =   -8 

Accordingly,  B2  -  4AC   =

                     81 - (-192) =

                     273

Applying the quadratic formula :

               9 ± √ 273 

   x  =    —————

                    12

  √ 273   , rounded to 4 decimal digits, is  16.5227

 So now we are looking at:

           x  =  ( 9 ±  16.523 ) / 12
