Answer:
Step-by-step explanation:
A quadratic equation has one root if the discriminant is 0.
That is we need for this particular question.
Compare the following to find :
The variable is representative of the variable
here.
Plug in into :
Subtract 4 on both sides:
Divide both sides by 16:
Reduce:
<u>Given</u>:
The quadratic equation is
We need to determine the solutions of the quadratic equation.
<u>Solution</u>:
Let us solve the equation to determine the value of x.
Adding both sides of the equation by 5x and 3, we get;
The solution of the equation can be determined using quadratic formula.
Thus, we get;
Thus, the two roots of the equation are and
Hence, the solutions of the equation are and
