A polynomial with rational coefficients has roots 5 and -6i. (The i is an imaginary number not variable). What is the polynomial

mars1129 [50]

Answer:

<em>The answer is</em> <em>{ $x^{3}$ -(5) $x^{2}$ (36)× $x$ -(180)</em>

Step-by-step explanation:

A polynomial with rational coefficients has roots 5 and -6i (There i is the

imaginary number not variable )

As we knew that imaginary no comes in pair . This means that if -6i is

one root then the other root will be 6i

So if we assume the lowest polynomial that is possible is given as

{ $x^{3}$ -(sum of all roots) $x^{2}$ +(roots taken two at a time)

$x$ -(product of all roots)

{ $x^{3}$ -(5+6i+(-6i)) $x^{2}$ +(5×6i +5×(-6i) +6i×(-6i))

$x$ -(5×6i×(-6i))

$i^2$ = -1

<em>{ $x^{3}$ -(5) $x^{2}$ (36)× $x$ -(180)</em>

<em> </em>The <u>general case</u> we assume that the three previous roots and rest roots

a4,a5,a6 ...............an

$x^n$ -(sum of all roots)× $x^{n-1}$ +(roots taken two at a

time) × $x^{n-2}$ - .......................................... (product of all roots)

PLEASE HELP ASAP 25 PTS + BRAINLIEST TO RIGHT/BEST ANSWER

Answer:

D) $y=(x-3)^2-3$

Step-by-step explanation:

The first step is to find the vertex.

Start with getting your coefficients:

a = 1, b = -6, c = 6

plug them into the equation $x = -b/2a$

$6/2$

$x = 3$

Plug that back into the original equation to get y = -3

The vertex is going to be (3, -3)

The equation for Vertex Form is given by $f (x) = a(x - h)^2 + k$

(a) being the coefficient in front of the $x^2$

(h) being the first point on the vertex (h,k) ({3},-3)

(k) being the second point on the vertex (h,k) (3,{-3})

$y=(x-3)^2-3$

!!!!!!! Why isn't A the correct answer? I am having trouble to reason why A is wrong so please help if can!

Answer:

d. x = -3

Step-by-step explanation:

<u /> $\sqrt{(x + 3)}$ ÷ (x+8)(x-2) = 0

f(x) / g(x) = 0

Variable x cannot be equal to any of the values −8,2 since division by zero is not defined. Multiply both sides of the equation by (x−2)(x+8).

<u /> $\sqrt{(x + 3)}$ = 0 ------ square both sides

x + 3 = 0

solve for x:

x = -3
