How would i factor this?
14u^2 - 33u - 5

(7u+1)(2u-5)

Step-by-step explanation:

miltiply the coefficient of u² and the integer -5 = -70

from basic intuition: factors are -35 and +2

(which when added gives -33 and multiplies to give 70)

14u² -35u +2u -5

7u(2u-5) +1(2u-5)

(7u+1)(2u-5)

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500
