Rewrite in factored form, do not solve
9x^2+21x-8=0

(3 x - 1) (3 x + 8)

Step-by-step explanation:

Factor the following:

9 x^2 + 21 x - 8

Factor the quadratic 9 x^2 + 21 x - 8. The coefficient of x^2 is 9 and the constant term is -8. The product of 9 and -8 is -72. The factors of -72 which sum to 21 are -3 and 24. So 9 x^2 + 21 x - 8 = 9 x^2 + 24 x - 3 x - 8 = 8 (3 x - 1) + 3 x (3 x - 1):

8 (3 x - 1) + 3 x (3 x - 1)

Factor 3 x - 1 from 8 (3 x - 1) + 3 x (3 x - 1):

(3 x - 1) (3 x + 8)

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

people grow faster than other people.
