How do I find the answer?

11Alexandr11 [23.1K]

First simplify the number part, 14/2 = 7/1
then the x part, $\frac{x}{x^ \frac{3}{4} } = x^ \frac{1}{4} 
$
y doesn't need to be simplified
then simplify the z part, z^-6 = z^6

put it all together...
$7x^ \frac{1}{4}y^ \frac{1}{3} z^6$

Which two values of x are the roots of the polynomial below? <br> x^2+5x+11

In-s [12.5K]

Answer:

x = -5/2 + i√19 and x = -5/2 - i√19

Step-by-step explanation:

Next time, please share the possible answer choices.

Here we can actually find the roots, using the quadratic formula or some other approach.

a = 1, b = 5 and c = 11. Then the discriminant is b^2-4ac, or 5^2-4(1)(11). Since the discriminant is negative, the roots are complex. The discriminant value is 25-44, or -19.

Thus, the roots of the given poly are:

-5 plus or minus i√19

x = -----------------------------------

2(1)

or x = -5/2 + i√19 and x = -5/2 - i√19
