N=3, zeros 4 and 2i, f(2)=-48 find nth degree polinomonal function

enot [183]

The degree is 3, the zeros are; 4, 2i, -2i and a point is (-48, 2)

For zeros; 2i, -2i <-- complex conjugates, always in pairs

$\frac{c}{a}=(2i)(-2i) 
$
= -4(i²=-1)
=5

$\frac{b}{a}=-(2i+(-2i))$
=0

Therefore the equation is; a( $x^{2}$ +5) <-- b value is zero

Rewrite the equation with all zeros;

a(x-4)(x²+5)=f(x) <-- put in coordinates of the points to find the value of x
a(2-4)(2²+5)=-48
a(2)(9)=-48
a=-48/18
a=-8/3

The final polynomial function is; (-8/3)(x-4)(x²+5)=f(x)

Hope I helped :)

X - 3= -21 <br>This is so confusing:(

Answer:

$\huge\boxed{x=-18}$

Step-by-step explanation:

In order to solve this, we are trying to find the value of $x$ . Basically, $x$ is a placeholder for a number that is unknown. Some number minus 3 is equal to 21.
