Answer:
7
Step-by-step explanation:
Substitute in numbers : 2(5)+3(6) /4
Combine Like Terms : 10+18/4 = 28/4
Answer : 7
2x2(2x+1)(2x-1) this is the answer I got.
The rule, letting d=discriminant:
d>0, two real solutions
d=0, one real solution
d<0, no real solution (but there are two imaginary solutions)
So if it has only one real solution, the discriminant is equal to zero.
