Question

please solve this problem as early as possible. ​

Answer 1

Step-by-step explanation:

solution:-x²-3x-28

            =x²-7x+4x-28

            =x(x-7)+4(x-7)

            =(x+4)(x-7)

             (x+4)(x-7)=0

Now,

(i)x+4=0  (ii)(x-7)=0  

  x=-4              x=7

thus, Zeroes are -4,7

Verify:-

Sum of zeroes = -4+7

                        =3

and -b/a=-(-3)/1

             =3

thus,Sum of zeroes=-b/a

Product of zeroes=-4*7

                             =-28

and, c/a=-28/1

            =-28

thus, Product of zeroes=c/a verified

I hope it helps you
