A variable is a letter in the equation.
A, B, and C dont have variables... unless a question mark is considered a variable at your school (I dont consider it a variable).
D has an x in the equation, so D has a variable.

it is 34 becuas u didvoed

Answer:
True
Step-by-step explanation:
Here, we want to check if the given equation does not intersect the x-axis
if it does not, then it has no real root
If the discriminant is less than zero, then it has no real roots and does not intersect the x-axis
The formula for the discriminant is;
D = b^2-4ac
In the question;
a = -1 , b = 6 , c = 10
so;
D = 6^2-4(-1)(10)
D = 36-40
D = -4
Since discriminant is less than zero, then there is no real root and the graph does not cross the x-axis
