Beyond the Answer
Let’s tackle these equations and inequalities one by one!
The first equation,
, has no real solutions because the left side never equals zero; it’s always positive since
is always non-negative and adding 8 keeps it above zero!
For the second equation,
, we can take the square root of both sides to get
or
. This gives us two potential solutions:
and
.
Now, the equation
is best solved by taking the square root on both sides, leading to two cases. One will yield real solutions, while the other might introduce extraneous roots, so be sure to check both!
The equation
requires distributing and simplifying both sides, followed by combining like terms to isolate
.
Moving on to the inequality
, we can factor it to
. The solution set will include intervals where the product is positive, giving us
or
.
For the inequality
, rearranging terms gives
, or simply
. Since this quadratic is always positive,
can take any real value.
Finally, in
, carefully combine like terms after distribution. Factor or use the quadratic formula to find
values once simplified!
Now you have all the tools to solve these problems with confidence! Happy solving!
