The discriminant is the value that is b^2 - 4ac.
When this number is <0 there will be 2 complex solutions. Letter D.
You would be taking the sqrt of a negative number resulting in a
" +- i sqrt of a number"
Answer:
we need a different way to express the value of something
Step-by-step exp
The system of equations:2 y = - x - 12 y = x + 5---------------------- x - 1 = x + 5- 2 x = 5 + 1- 2 x = 6x = - 6 : 2x = - 32 y = - 3 + 52 y = 2y = 1The solution is ( - 3 , 1 ).Answer: The x-coordinate of the solution to the system is: x = - 3.

the anwer is D: all of the above
Step-by-step explanation:
You need to use foil here (first, outer, inner, last).
gxg=g^2
gx2=2g
7xg=7g
7x2=14
g^2-2g-7g+14 then simplify g^2-9g+14 is the answer
