What are the solutions of this quadratic equation? x2 + 8x + 3 = 0

-4 + √13 ; -4 - √13

Step-by-step explanation:

x² + 8x + 3 = 0

(x² + 2(x)(4) + 4²) - 4² + 3 = 0

(x + 4)² -16 + 3 = 0

(x + 4)² = 13

x + 4 = √13

x = -4 + √13

x + 4 = -√13

x = -4 - √13

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
