Answer:
Inverted parabola
Two complex solution
Step-by-step explanation:
any quadratic equation can be expressed in terms of ax^2 + bx + c = 0
It has two solutions which can be found using formula
We know that for any value inside the square root function
if it is positive its solution will be real number
for example we can have two real solution -3 and 3
if it is negative its solution will be complex number
for example we can have two complex solution
expressed in term of a + ib or a - ib
------------------------------------------------------------------------------------------
Given in the problem
we have ax^2 - bx + c
so its solution will be
Since in this expression it is given in problem statement that b^2 - 4ac < 0 which will be a negative number and for negative number, its square root is complex number.
also X has two values as given above it will have two solution
hence it will have two complex solution based on above discussion.
Also for any quadratic equation shape of its curve if plotted on coordinate plane is parabolic.
If it has complex solution then curve of such expression will not pass through X axis
Answer:
A. 9x^4 and 3x^5y
Step-by-step explanation:
there are two ways to solve this:
first way:
You can solve this my substituting numbers for x and y in this case i used 2 for x and 3 for y and see which one is equal to the original equations
the second way is the regular way
when you add or subtract numbers with variables and exponents you want to add the constants and add the exponents in this case is the same as
=
and you can do the same process for subtraction
=
