Choose the polynomial that is written in standard form. 2x2y2 + 3x4y + 10x6 4x4y2 + 6x3y5 + 10x −3x8y2 + 9x2y + 10x2 −7x6y2 + x3y8 + 10x2
standard form has decreasing degrees of x and increasing degrees of y
so the one that has that property is your answer
What one do you think?
I don't know how to look at the decreasing degrees of x and increasing degrees of y
look at the exponents of x..if the exponents are decreasing for every term, then that has decreasing degree
for example \(x^3 + x^2 + x + 1\)
so that's decreasing
is it B?
if there is no y...that means the degree of y for that term is 0
theres a y in every single one
is this B? 4x4y2 + 6x3y5 + 10x feels like something is missing
the degrees I cant put them on here
http://tutorial.math.lamar.edu/Classes/Alg/Polynomials.aspx#Pre_Poly_Ex2_a search that page for polynomials in two variables
i guess you ad xs exponent and y's exponet in each term then take that sum and put it in decreasing order.
|dw:1372894843615:dw| −3x8y2 + 9x2y + 10x2 is right
The answer would be C Jaderbrown. Polynomials go from highest degree to smallest. To find the degree, of one of its terms you would do the following.. −3x8y2 + 9x2y + 10x2 \( -3x^8,^2 \) = degree 10 8+ 2 = 10
That is \( -3x^8y^2 \) = 10 degree because 8+2 = 10, which when times you add exponents. You got it Jaderbrown? Highest degree to lowest.
yes I get it thank you :)
