The sum of two polynomials is 8d5 – 3c3d2 + 5c2d3 – 4cd4 + 9. If one addend is 2d5 – c3d2 + 8cd4 + 1, what is the other addend?

velikii [3]

By subtracting the given addend to the sum, we see that the other addend is:

$6d^5 - 2c^3d^2 + 5c^2d^3 - 12cd^4 - 8$

<h3>How to get the other addend?</h3>

We know that the sum of two polynomials is:

$8d^5 - 3c^3d^2 + 5c^2d^3 - 4cd^4 + 9$

One of the addends is:

$2d^5 - c^3d^2 + 8cd^4 + 1$

To get the other addend, we can subtract the given addend to the sum:

$8d^5 - 3c^3d^2 + 5c^2d^3 - 4cd^4 + 9 - (2d^5 - c^3d^2 + 8cd^4 + 1)\\\\6d^5 - 2c^3d^2 + 5c^2d^3 - 12cd^4 - 8$

Then we can conclude that the other addend is:

$6d^5 - 2c^3d^2 + 5c^2d^3 - 12cd^4 - 8$

5x2 + 5x + 8 = 0 ?<br> What is the complex solution to the quadratic equation

emmainna [20.7K]

Answer:

$\frac{-1+135i}{2}$ , $\frac{-1-135i}{2}$

Step-by-step explanation:

you use the quadratic equation: (-b ± $\sqrt{b2 - 4ac}$ ) ÷ 2a

in this case, a = 5, b = 5, c = 8

inside the radical will be -135, hence using 135i where 'i' equals -1

Write a quadratic function with zeroes 0 and 8.

Jlenok [28]

Answer:

$x^2-8x=0$

Step-by-step explanation:

the quadratic function should be as follows:

$x^2-8x=0$

Now let's confirm that the zeros of the function are 0 and 8

$x^2-8x=0=x(x-8)=0$

Therefore we can see that if x = 0

$0^2*8*0=0\\0=0$

the equation is fulfilled

And we also have $(x-8)$

for this expresion to be equal to zero:

$x-8=0\\x=8$

thus, if x = 8

$8^2-8*8=0\\64-64=0\\0=0$

the equation is also fulfilled

The zeros of the quadratic function $x^2-8x=0$ are 0 and 8.
