Answer:
-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.
