Answer:
(-1,9)
Step-by-step explanation:
union contains both sets.
I think it is a but I’m not sure
√81 is farther to the right becaue 2.5^2 = 6.25 and <span>√81 is 9</span>
Consider the expression
To factorize the expression in the denominator we use difference of squares:
To factorize
we use the following method:
where a, b are 2 numbers such that a+b= -1, the coefficient of x,
and a*b= -6, the constant.
such 2 numbers can be easily checked to be -3 and 2
(-3*2=6, -3+2=-1)
So
for x>2
thus
for x>2,
Answer:
for x>2
, (but the expression is never 0)
<span>each missing number is the square of half the coefficient of the 1st order term</span><span>
(5/2)² = 25/4 </span>
