Some five-digit numbers, such as 20002 and 72027, read the same forward and backward. if a boy selects a number from all five-digit numbers, find the probability that it will read the same forward and backward.

well the answer to that is xoxoxo

step-by-step explanation:

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
