Find an nth degree polynomial function with real coefficients satisfying the given conditions. n=3;
-2 and 8+4i are zeros;
f(-1)=97

f(x)=

please help, I went step by step when doing a similar question and I was way off. Much obliged.

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%

first 15 divide by 2 = 7.5

100 divided by 7.5 is 13.

15 / 2 = 7.5

100 / 7.5 = 13.
