To answer the question above, divide the given second degree polynomial by the given solution. You may either use the long division or the synthetic division. Using the long division,

(x^2 - 2x -15) / (x + 3) = x - 5

Thus, the other solution is x - 5 or x = 5 which is the last one from the given choices.

Answer from: Quest

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
