Degree 3 polynomial with zeros -7, 3i, and -3i

d1i1m1o1n [39]

A polynomial having degree 3 with zeros -7, 3i, and -3i is:
x³+ 7x² - 9x - 63

The correct answer is an option (A)

In this question, we need to find the polynomial whose degree is 3 polynomial and zeros are -7, 3i, and -3i

The zeros of the required polynomial = -7, 3i, and -3i

This means, the roots of the polynomial = (x + 7), (x - 3i) and (x + 3i)

We know that in complex numbers, i = √-1

So, 3i = 3√-1

= √-9

i.e., the roots of the polynomial are (x + 7), (x - √-9) and (x + √-9)

And the polynomial would be,

(x + 7)(x - √-9)(x + √-9)

= (x + 7)(x² - (√-9)²)

= (x + 7)(x² - (-9))

= (x + 7)(x² + 9)

= x³+ 7x² - 9x - 63

Therefore, a polynomial having degree 3 with zeros -7, 3i, and -3i is:
x³+ 7x² - 9x - 63

The correct answer is an option (A)

Can someone please show me how to work out this problem.

poizon [28]

ok so to divide by a binomial you frist split the variable and the whole numbers down the middle, then you have t^2, t on one side and -13, -4 on the other

then you would divide both sides, dividing the numerator by the denominator, and that is your answer

iragen [17]

Given that,

Alonzo is $120 in debt. He makes $15 per hour. He wants to have at least $75 left over after he has paid off his debt.

To find,

The inequality and the solution.

Solution,

Let he make $x per hour. Here, $120 is fixed. $15 is added per hour.

ATQ,

$120 + 15x\ge 75$

For atleast, we use $\ge$ .

Subtract 120 from both sides.

$120 + 15x-120\ge 75-120\\\\15x\ge -45\\\\x\ge -3$

So, the required answer is greater than -3.

Hope you understand, and never stop striving to learn!

Step-by-step explanation:

The sample mean is both values added together then divided by 2.

$46.63

The margin of error is the low value divided by the high value * 100% =76.8% (then you have to minus this from 100% so the margin of error is 23.2%)
