I’ve been stuck on this khan for hours already can’t seem to figure it out, it’s just adding and subtracting polynomials but it’s supposed to equal a polynomial in standard form :( please help me !!

Step-by-step explanation:

 polynomial is said to be in its standard form, if it is expressed in such a way that the term with the highest degree is placed first, followed by the term which has the next highest degree, and so on. You can observe that in this standard form of a polynomial, the exponents are placed in descending order.

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)
