What are all of the real roots of the following polynomial? f(x) = x4 - 13x2 + 36

GREYUIT [131]

ANSWER

A. -3, -2, 2, and 3

EXPLANATION

The given polynomial function is,

$f(x) = {x}^{4} - 13 {x}^{2} + 36$

To find the real roots, we equate the function to zero to obtain;

${x}^{4} - 13 {x}^{2} + 36 = 0$

We can solve this equation as a quadratic equation in
${x}^{2}.$

Thus we rewrite the equation as,

$({x}^{2})^{2} - 13 {x}^{2} + 36 = 0$

We split the middle term to get,

$({x}^{2})^{2} - 9 {x}^{2} - 4 {x}^{2} + 36 = 0.$

We factor to get,

${x}^{2} ( {x}^{2} - 9) - 4( {x}^{2} - 9) = 0$

We factor to get,

$( {x}^{2} - 9)( {x}^{2} - 4) = 0$

Either

${x}^{2} - 9 = 0$
or

${x}^{2} - 4 = 0$

$x = \pm \sqrt{9} \: or \: x = \pm \sqrt{4}$
$x = \pm3 \: or \: x = \pm2$

$x=-3,-2,2,3$

The correct answer is A

A sneeze can travel up to 100mi/h how many feet per second is this a sneeze can travel up to 100m/h how many feet per second is

JulsSmile [24]

Ok first you have to convert 100 miles to feet.

A mile is 5,280 feet
100x5,280
528,000

Thats how much feet per hour. Now we need to find feet per second. So lets divide 528,000 by 60

528,000/60
8,800

Now we know 8,800 is how much feet per minute now we divide it once more by 60 to find feet per second.

8,800/60
146 2/3

So your answer is 146 2/3ft/sec
