x=13/2
Answer:
4
Step-by-step explanation:
The given polynomial is :
p(x) = -2a⁴+8a³-9a
We need to find the degree of the polynomial.
Degree of the polynomial = degree is the value of the greatest exponent.
Here, the maximum value of the exponent is 4 in -2a⁴.
It means,
Degree of the polynomial = 4
Answer:
11/30
Step-by-step explanation:
You need to convert everything to a common denominator, so you would change everything into x/30 so 7/10 is equal to 21/30 and 1/3 is equal to 10/30 so you would just subtract 21-10 and get 11/30
X^3 + 8 = x^3 + 2^3, a sum of two cubes.
So it can be factorised using the sum of two cubes rule...
a^3 + b^3 = (a + b)(a^2 - ab + b^2).
Therefore
x^3 + 8 = (x + 2)(x^2 - 2x + 4).
Hope this helps
