Answer:

6.25

Step-by-step explanation:

Find b, b= 5

Need (b/2)^2 = (5/2)^2 = 6.25

x^2+5x +6.35 =6.25

Then you can factor...

With love,

Hope :)

Which algebraic expression is a polynomial with a degree of 5?

katrin [286]

The Degree is the largest exponent of that variable.

Let's get started :

$3x^5 + 8x^4y^2 - 9x^3 y^3 - 6y^5$

Here, the largest exponent is from $8x^4y^2$ . It's 4+2 = 6.

$8y^6 + y^5 - 5xy^3 + 7x^2y^2 - x^3y - 6x^4$

Here, the largest exponent is 6.

$-6xy^5 + 5x^2y^3 - x^3y^2 + 2x^2y^3 - 3xy^5$

Here, the largest exponent is also 6. x itself is considered as exponent 1. So 1+5 = 6.

At last, let's check the second option,

$2xy^4 + 4x^2y^3 - 6x^3y^2 - 7x^4$

Here the largest exponent is 5.

In short, the answer would be :

$\boxed {\boxed{2xy^4 + 4x^2y^3 - 6x^3y^2 - 7x^4}}$

Hope this helps !
