Answer:

c) (x + 2)(x + 2i)(x - 2i)

Step-by-step explanation:

x^3 + 2x^2 + 4x + 8

= (x^3 + 2x^2) + (4x + 8)

= x^2( x + 2) + 4(x + 2)

= (x + 2)(x^2 + 4)

= (x + 2)(x^2 - 4i^2)  ---------------------------->(i^2 = -1)

= (x + 2)(x + 2i)(x - 2i)

Write 2x3 − 3x2 + x5 in standard form. What is the classification of this polynomial by its degree? by its number of terms?
andrew-mc [135]

Answer:

  x⁵ +2x³ -3x², degree 5, 3 terms

Step-by-step explanation:

We assume you intend your expression to be ...

  2x³ -3x² +x⁵

The superscript numbers are exponents. Each indicates the degree of the term. In standard form, terms are listed in decreasing order by degree:

  x⁵ +2x³ -3x² . . . . standard form

The degree of the polynomial is the degree of the highest-degree term: 5.

The number of terms is the number of products in the sum: 3.

mart [117]
Let, the number = x
It would be: x + 15 = 2x - 56
2x - x = 15 + 56
x = 71

In short, Your Answer would be 71

Hope this helps!
