I'm not sure if that's x=4 or x= -4, but I'll solve both.
x=4:
11(4) - 4 = 44 - 4 = 40
x = -4:
11(-4) - 4 = -44 -4 = -48
Have an awesome day! :)
X2=x2+2x+9
x2-x2=2x+9
2x+9=0
2x=-9
x=-9/2

Step-by-step explanation:
Answer:
The discriminant equals to 0
Step-by-step explanation:
We have to remember our discriminant rules;
d > 0, we have 2 real roots
d = 0, we have 1 real root
d < 0, we have 2 complex roots
