4x^5+2x-1 would be an example, fifth dregree means the highest exponent is 5. hope this helps.
Answer:
36
Step-by-step explanation:
x^2 + 12 x = 40
To complete the square, take the coefficient of the x term
12
Divide by 2
12/2 = 6
Square it
6^2 = 36
Add 36 to each side
The answer is high im pretty sure
D x= -9
Y=9
Because 4(-9)+45=9
I just put in each one and d got it right.
