Step-by-step explanation:
Answer:
Let’s assume a,b,x real. Then all we require of y is y2 is real, so y
can be real or purely imaginary, but not an arbitrary complex number.
The hard question in these is always, do we need ±
? Here the answer is yes. It’s basically asking is there one solution or two, and in this problem we have two.
Solve for y
: x=a−2by2
Step-by-step explanation:
Answer:
x = 12
Step-by-step explanation:
Since the top line is equal to the bottom, you make the equation -
x + x + 4 = x + 16
You subtract an x on both sides because there is one on each side -
x + 4 = 16
Then you subtract the 4 from both sides to get x by its self, which makes
x = 12
