Simple...

y= $x^{2} -9$

$y= x^{2} -9$

It's quite easy to see $x^{2} = x^{2}$

Thus, any value of x makes the equation true.

Thus, your answer.

Write x^2-12x+8 in vertex form.

solong [7]

The vertex form: y = a(x - h)² + k

y = ax² + bx + c then h = -b/2a and k = f(h).

y = x² - 12x + 8

a = 1; b = -12; c = 8

h = -(-12)/(2·1) = 12/2 = 6

k = f(6) = 6² - 12·6 + 8 = 36 - 72 + 8 = -28

Answer: y = (x - 6)² - 28.

Which expression is equivalent to 4 sqrt 24x^6y/128x^4y^5

Stels [109]

The first step for finding out if the expression provided is equivalent to $\sqrt{4}$ is to reduce the fraction with $x^{4}$ .
$\frac{24 x^{2} y}{128 y^{5} }$
Now reduce the fraction with y.
$\frac{24 x^{2} }{128 y^{4} }$
Finally,, reduce the fraction with 8 to get your final answer.
$\frac{3 x^{2} }{16 y^{4} }$
Let me know if you have any further questions.
