what is the simplified expression of the following polynomial: xy4 + 5y7 - (6xy + 7y7) - x8y2 + (-3xy4)
Lunna [17]

This polynomial would simplified as: -2y^7-2xy^4-x^8y^2-6xy (I'm assuming you meant to square the answers)

If you didn't the answer would be: -30xy-14y

But I'm pretty sure you meant to put the first one!

The integers X and Y fulfil the condition 2X=5Y. Which can be considered for X+Y?
KiRa [710]

Answer:

X + Y could equal to 1 \frac{2}{5}X or 3 \frac{1}{2}Y.

Step-by-step explanation:

2X = 5Y

Y = \frac{2}{5}X

X = \frac{5}{2}Y

Hence, X + Y could equal to X + \frac{2}{5}X = 1 \frac{2}{5}X or Y + \frac{5}{2}Y = 3 \frac{1}{2}Y.

Hence, X + Y could equal to 1 \frac{2}{5}X or 3 \frac{1}{2}Y.

Help with this question, ASAP PLEASE!! SHOW YOUR WORK!!

Simplest polynomial function is x^4-x^3-11x^2+9x+18.

Solution:

Given data:

Zeroes are 3i, –1, 2.

3i is a complex root of the function.

If 3i is a zero of the polynomial then –3i is also a zero of the polynomial.

Therefore zeroes are 3i, –3i –1, 2.

By factor theorem,

If a is zero of the function, then (x – a) is a factor of the polynomial.

So, the factors are (x – 3i), (x + 3i), (x + 1), (x –2).

On multiplying the factors, we get the polynomial.

(x - 3i) (x + 3i) (x + 1) (x -2)

            =(x^2+3ix-3ix+(3i)^2)(x^2-2x+x-2)

            =(x^2-9)(x^2-x-2)

Since the value of i^2=-1

            =x^2(x^2-x-2)-9(x^2-x-2)

            =x^4-x^3-2x^2-9x^2+9x+18

            =x^4-x^3-11x^2+9x+18

Simplest polynomial function is x^4-x^3-11x^2+9x+18.
