Answer:

negative square root will result in zero x-intercepts

Step-by-step explanation:

there are no x-intercepts because if you use the quadratic formula on the equation you get a negative square root which results in zero x-intercepts

in this case, a=-1, b=4, c=-12

[-4±√4² - 4(-1)(-12)] / 2(-1)

= [-4 ± √16-48] / -2

= -4 ± √-32 / -2

What is the simplified form of StartRoot StartFraction 72 x Superscript 16 Baseline Over 50 x Superscript 36 Baseline EndFractio

Iteru [2.4K]

The simplification form of the provided expression is 6/5x¹⁰ option first is correct.

<h3>What is an expression?</h3>

It is defined as the combination of constants and variables with mathematical operators.

We have an expression:

$\rm = \sqrt{\dfrac{72x^{16}}{50x^{36}}}$

$\rm = \sqrt{\dfrac{72}{50}} \sqrt{\dfrac{x^{36}}{x^{16}}}$

$\rm = \sqrt{\dfrac{36\times2}{25\times2}} \sqrt{\dfrac{x^{36}}{x^{16}}}$

$\rm ={\dfrac{6x^{8}}{5x^{18}}}$

$\rm ={\dfrac{6}{5x^{10}}}$

Thus, the simplification form of the provided expression is 6/5x¹⁰ option first is correct.
