Answer:
Step-by-step explanation:
-2x²=-8x+8 means : -2x²+8x-8
the discrinant of the quadratic equation is : delta = b²-4ac
when a=-2 and b=8 and c= -8
calculate delta = (8)²-4(-2)(-8) ......continu
The total number of points would be equal to 5n.
You would simply multiply 5 by the amount of questions. In this case, we do not know the amount, so we can use the variable n.

28 is 4 times 7, so we will rewrite it like that.

7 is 7 times 7, so we will rewrite it like that.

So the simplest form is,
