Answer: -57

Step-by-step explanation:

15 + ( - 72)

Distribute

15 - 72

When this happens, you subtract the smaller number by the bigger one, then put the sign that was on the bigger number on what you get.

72 - 15 = 57

Put a negative sign on 57

-57

15 + (-72) = -57

Find an nth degree polynomial function with real coefficients satisfying the given conditions.

damaskus [11]

Step-by-step explanation:

Our roots are 3, and i so our roots form

will be

$(x - 3)(x - i)$

Since i is one root, it conjugate, must be the other.

so we have

$(x - 3)(x - i)(x + i)$

Simplify

$( {x}^{2} + 1)(x - 3)$

${x}^{3} - 3 {x}^{2} + x - 3$

So the function is

$x {}^{3} - 3 {x}^{2} + x - 3$
