The other solution to the equation is -3.
Step-by-step explanation:
Given equation is;
5x²+bx+12=0
One solution is -4/5
We will put this solution in Eqn to get the value of b first,
Multiplying each term by 5
Dividing both sides by -4
Putting b=19 in given Eqn
5x²+19x+12=0
Here,
a=5 , b=19 , c=12
Using quadratic formula,
Either, or,
The other solution to the equation is -3.
