Question 162093: I am completely lost on this worksheet and have no book. Please help.
Find the value of the discriminant for 9x^2+1=6x. Then describe the number and type of roots for the equation.
Thanks

9x^2+1=6x
First let's but this in standard form;

discriminant;

a=9
b=-6
c=1
Now we plug these in;

36-36=0
Since the discriminant is 0, there is one real root.
Now use the discriminant in the quadratic equation to find the number;

If the discriminant is negative, there are no real roots;
If the discriminant is positive, there are two real roots.
