One of the solutions to the equation 5x^2+bx+12=0 is − 4/5 . find the other solution.

-3 is the other solution.

Step-by-step explanation:

As, is One of the solutions of the equations , So, it should satisfy the equation.

Putting  in equation 5 + bx + 12 = 0 ,

We get,

               5××   +    b×   +  12 = 0.

 5×  +     +  12 = 0.

 After solving ,    16 - 4b  + 60  = 0.

                             4b = 76

                                b = 19.

So, the equation is  5  +  19x  + 12 = 0.

      After factorizing , 5  + 15x + 4x + 12 = 0.

                                    5x(x+3) + 4(x+3) = 0

                                     (5x+4)(x+3) = 0

Clearly the roots of the equation are  -3 and .

So, the other solution is -3.
