Answer:
Step-by-step explanation:
hello :
if x1 and x2 this zero for ax²+bx+c you have : x1 = 1 /x2 means :x1 × x2 =1
but : x1 × x2 = c /a
in this exercice : a =8 and b = -13 and c = - 4k
so : c/a =-4k/8
so : -4k/8 = 1
-4k = 8 k = 8/-4 k = -2
this polynomial is : 8x²-13x +8

Probability<span>: </span>Complement<span>. </span>Complement<span> of an </span>Event: All outcomes that are NOT theevent<span>. So the </span>Complement<span> of an </span>event<span> is all the other outcomes (not the ones we want). And together the </span>Event and its Complement<span> make all possible outcomes.</span>
