If x^2+1/x^2

(x + 1/x)² = x ² + 2 + 1/x ² = 10 + 2 = 12

==>   x + 1/x = ±√12

25% is the answer

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%
