What is the degree of the polynomial 5x + 4x^2 + 3x^3 – 5x?

a. 1
b. 2
c. 3
d. 4

C option

Step-by-step explanation:

Degree is highest power of the variable,,

here 3 is highest power of x..

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
