I'm assuming the given problem is (9+6i) - (1+3i)

If that assumption is true, then this is what the steps look like

(9+6i) - (1+3i)

9+6i - 1-3i

(9-1)+(6i-3i)

(9-1)+(6-3)i

8+3i

<h3>Answer: 8+3i</h3>

A polynomial function upper P left parenthesis x right parenthesis with rational coefficients has the given roots. Find two addi
mylen [45]

Given that a polynomial function P(x) has rational coefficients.

Two roots are already given which are i and 7+8i,

Now we have to find two additional roots of P(x)=0

Given roots i and 7+8i are complex roots and we know that complex roots always occur in conjugate pairs so that means conjugate of given roots will also be the roots.

conjugate of a+bi is given by a-bi

So using that logic, conjugate of i is i

also conjugate of 7+8i is 7-8i

Hence final answer for the remaining roots are (-i) and (7-8i).

Answer is : 8v^3+ 14v^2+11v+3
For cubic feet

Solution

Formula : volume base area x height

So base area = 4v^2 +5v+3
Height = 2v+1


So multiply

Volume =(4v^2+5v+3) x(2v+ 1)

The rest is below

H(x) = x + 1 k(x) = x - 2 (h + k)(2) =​
barxatty [35]

h(x) = x + 1

k(x) = x - 2

_________________________________

(h + k)(x) = h(x) + k(x)

(h + k)(x) = (x + 1) + (x - 2) \\

(h + k)(x) = x + 1 + x - 2

(h + k)(x) = 2x - 1

(h + k)(2) = 2(2) - 1

(h + k)(2) = 4 - 1

(h + k)(2) = 3

And we're done.....♥️♥️♥️♥️♥️
