Question

Someone please tell me if this is right or not!!

Answer 1

Answer:

close countess

Step-by-step explanation:

remember that the sign has to be postive so just change all the signs ,  then,   you'll have a leading coefficient of  +1,  in front of the $x^{2}$,  the 5 is in front of the 2nd term,  they were just trying to trick you with that.   the last answer is good     :)

Answer 2

The degree and standard form are correct, good job!
For the leading coefficient, I would see why you think it’s 5 since the highest number in front of x
but the definition of leading coefficient is the number of highest power of x
In this case it would be -x^2 is the higher power making -1 the leading coefficient
Hope this help, let me know if you have any question or concerns !
