the idea behind the completion of the square is simply using a perfect square trinomial, hmmm usually we do that by using our very good friend Mr Zero, 0.
if we look at the 2nd step, we have a group as x² - x, hmmm so we need a third element, which will be squared.
keeping in mind that the middle term of the perfect square trinomial is simply the product of the roots of "a" and "b", so in this case the middle term is "-x", and the 1st term is x², so we can say that
so that means that our missing third term for a perfect square trinomial is simply 1/2, now we'll go to our good friend Mr Zero, if we add (1/2)², we have to also subtract (1/2)², because all we're really doing is borrowing from Zero, so we'll be including then +(1/2)² and -(1/2)², keeping in mind that 1/4 - 1/4 = 0, so let's do that.
The answer is B. 1. Exponents<span> add when you have the same base. This works for any </span>number<span> x that you want to plug in except for x = </span>0<span>,because </span>0/0<span> is indeterminate (it is like dividing </span>zero<span> by </span>zero<span>). No matter what </span>number<span> we use when it is </span>raised<span> to the </span>zero<span> power it will always be </span>1<span>.</span>

Answer:
1/5
Step-by-step explanation:
Of the 5 spinner sections, 2 are less than 3.
P(less than 3) = 2/5
Of the 2 sides of the coin, 1 is tails.
P(tails) = 1/2
The compound probability is therefore:
P = 2/5 × 1/2
P = 1/5
