X²+4x+8=0
use the quadratic formula: (sorry cannot type it here)
√(b²-4ac)=√(4²-4*1*8)=√(16-32)=√(-16)=+/- 4i
x=(-4+4i)/2 or (-4-4i)/2
x=-2+2i or x=-2-2i
the answer is A
Answer:
b. 23
Step-by-step explanation:
Using factor trees
23 115

115= 23
If you circle the common factors in each factor tree, you get 23.
Therefore your answer is B
