The answer would be 4
(Positive 4 btw)
Answer:
x^2 - 2xi - 4x +8i
Step-by-step explanation:
(x -4) (x -2i) (x+2i)
Answer:
B
Step-by-step explanation:
yes, 12² + 13² = (
)²
144 + 169 = 313
313 = 313
For f(x)=ax^2+bx+c
the axis of symmetry is -b/2a
f(x)=2x^2+4x+2
a=2
b=4
-4/(2*2)=-4/4=-1
the axis of symmetry is x=-1
B
I can't understand what you wanted with the second question (or if that is even a question), but the answer to the first one is 42.
