The right side of the equation can be rewritten in terms of p as 4p (4p = 4(x^2 +6) = 4x^2 +24)

Now you have (x^2 +6)^2 - 21 = 4p

Replace (x^2 +6) with p

p^2 - 21 = 4p

Subtract 4p from each side:

p^2 - 21 -4p = 0

Rewrite the expression to get p^2 - 4p -21 = 0

Which statement is NOT true?

elena-s [515]

If x ^ 2 = 100, then x = 10.

For this case what you should know is the correct clearance of the following equation:
$x ^ 2 = 100
$
We then have two possible solutions:
$x=+/- \sqrt{100}$
Rewriting we have:
$x=+/-10$
Therefore, the solutions are:
$x1=10

x2=-10$
Answer:
A statement that is NOT true is:
If x^2 = 100, then x = 10.
