Step-by-step explanation:

f(x) * g(x)= (3x^2-4x-5)(11x-3)

33x^3-44x^2-55x-9x^2+12x+15

33x^3-53x^2-43x+15

is the sum of two polynomials of degree 5 always a polynomial of degree 5? Give an example to explain your answer
ddd [48]
A counter example is

f(x)=5x^5+2x^3+3x
g(x)=-5x^5-x^4+x^2-4

Then f(x)+g(x) = -x^4+2x^3+x^2+3x-4  which is a polynomial of degree 4.

So the answer is no.  Counter-example is given above.

The value of x should be greater than or equal to -2. The number line from -2 to the entire right till ∞ of the number line will satisfy this condition.

<h3>What is a number line?</h3>

A number line is just that – a straight, horizontal line with numbers placed at even increments along the length. It’s not a ruler, so the space between each number doesn’t matter, but the numbers included on the line determine how it’s meant to be used.

The value of x that will satisfy this condition can be found by simplifying the given inequality. Therefore, The given inequality can be simplified as,

4x + 1 - 1 ≥ -8

4x ≥ -8

x ≥ -2

Hence, the value of x should be greater than or equal to -2. The number line from -2 to the entire right till ∞ of the number line will satisfy this condition.
