Write the quotient and the remainder for the following (x²-10x+24)÷(x+6)<br>solve and answer plz ​
elena-s [515]

Answer:

On dividing, we found that the quotient is (x-4) and the remainder is equal to 0.

Step-by-step explanation:

We need to find the quotient and the remainder for the following (x²-10x+24)÷(x+6).

The numerator is (x²-10x+24) and the denominator is (x+6). It can be written as :

\dfrac{x^2-10x+24}{x+6}=\dfrac{(x-4)(x-6)}{(x+6)}\\\\=(x-4)

On dividing, we found that the quotient is (x-4) and the remainder is equal to 0.

Write a polynomial functionſ of least degree that has rational coefficients, a leading coefficient of 1, and the zeros 1,3, and
otez555 [7]

Answer:

f(x) = x^{4}  -  8x^{3}  + 24x^{2}  - 32x  + 15

Step-by-step explanation:

First of all, if 2 - i is a zero, then so is 2 + i

All you need to do now is multiply (x - 1)(x - 3)(x - 2 + i)(x - 2 - i)

I will do part of that multiplication

(x - 2 + i)(x - 2 - i) = x^{2} - 2x - xi - 2x + 4 + 2i + xi - 2i - i^{2}

                           = x^{2} - 4x + 5

So, now (x - 1)(x - 3)(x^{2} - 4x + 5) =  x^{4}  -  8x^{3}  + 24x^{2}  - 32x  + 15

I will let you finish that multiplication.  I did some and you can do some.  OK?
