Find the degree of this polynomial a^3+3a^2-5a answer because i don't know how to do ! i need to do this by tomorrow morning you : )

The degree of the given polynomial is 3

Step-by-step explanation:

Given polynomial  

The above polynomial is trinomial which has power of 3.

To find the degree of the polynomial we have to check the powers of terms and analyse highest power

The degree of a polynomial is the highest of the degrees of its monomials (individual terms) with non-zero coefficients. The degree of a term is the sum of the powers of the variables ,it is a non-negative integer.

The degree of the given polynomial   is 3

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
