If the polynomial is of the form x^2+bx+c (ie., no factor in front of the x^2!!) then you can look for numbers that add up to b and multiply to c.
So in this case: what two numbers, when added, give -2 and when multiplied, give 1? A little trial and error gives you -1 and -1.
So the factorization is (x-1)(x-1). This is zero for x=1. There is only one zero.
Answer:
x=2
Step-by-step explanation:
12-10=2
A. one bc the answer a is only one letter
A million seconds is not that long. My next birthday is in 1,296,000 seconds
from now, and I have already lived more than 2.3 billion seconds !
(1,000,000 seconds) x (1 day / 86,400 seconds) =
11days 13hours 46minutes 40seconds .
It's possible that you might have one birthday within that length of time,
but it's not guaranteed. It would have to be the RIGHT million seconds.
If that's been your whole life so far ... you are 1 million seconds old ..,
then you have not had your first birthday yet.
So to find value of x , we have to apply Linear Pair.
