What are the solutions of the equation x4 + 6x2 + 5 = 0? Use u substitution to solve. x = i and x = iStartRoot 5 EndRoot x = plus-or-minus i and x = plus-or-minus iStartRoot 5 EndRoot x = plus-or-minus StartRoot negative 1 EndRoot and x = plus-or-minus StartRoot negative 5 EndRoot x = plus-or-minus Negative 1 and x = plus-or-minus -StartRoot 5 EndRoot

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%

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1

doubled
