Use the quadratic formula to determine the exact solutions to the equation. 2x2−9x+1=0

I feel like it's either b or d. I keep getting the same answer when I solve it but the thing is, it's not on the answer choices. my answer was (9 ± √ - 89 )/ 4
but it's not there :((

step-by-step explanation:

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%
