3x + 7(3x+4)

Distribute:

=3x + (7)(3x) + (7)(4)

=3x + 21x + 28

Combine like terms:

=3X + 21X +28

=(3x + 21x) + (28)

=24x +28

Given that (x + 2) is a linear factor of the polynomial x3 + 4x2 + x – 6, what are the other two linear factors?A. (x – 1) and (
kkurt [141]

The other two linear factors of the polynomial x³ + 4x² +x -6 are; Choice A: (x – 1) and (x + 3)

<h3>Polynomial division</h3>

By ling division of polynomials, it follows that the division of polynomial x³ + 4x² +x -6 by x +2 yields the quadratic expression;

  • x² + 2x -3.

On this note, the factorisation of the quadratic expression above yields factors;

  • (x – 1) and (x + 3)

Which expression is equivalent to x^4 + 4x^2 - 45?
Nikitich [7]

Answer:

( {x}^{2}  - 5)( {x}^{2}  + 9) = 0

Step-by-step explanation:

The given expresion is

{x}^{4}  + 4 {x}^{2}  - 45 = 0

We can rewrite this as:

({ {x}^{2}) }^{2}  + 4 {x}^{2}  - 45 = 0

We obtained a quadratic equation in x²

Let us split the middle term to get:

({ {x}^{2}) }^{2}  + 9 {x}^{2}  -  5{x}^{2}  - 45 = 0

We factor by grouping to get:

{x}^{2} ( {x}^{2}  + 9) - 5( {x}^{2}  + 9) = 0

We factor further to get:

( {x}^{2}  - 5)( {x}^{2}  + 9) = 0

The correct answer is A.
