Question

Which of the following shows 2x^3y - 3x^2 + 7y^2x - 12y written in standard form?

A. 2x^3y + 7y^2x - 3x^2 - 12y

B. -12y + 7y^2x - 3x^2 + 2x^3y

C. 7y^2x - 12y + 2x^3y - 3x^2

D. -12y - 3x^2 + 7y^2x + 2x^3y

Answer 1

A. 2x^3y + 7y^2x - 3x^2 - 12y

Answer 2

look at the powers say in first term 2x^3y the combined power is 4
then next term it is 3

Answer 3

Yep, arrange terms in order of degree (xy^2 would be of degree 3, since you'd add the total exponents)

Answer 4

the power keeps on decreasing .

Answer 5

hence a is in standard form

Answer 6

are you clear with this @BasedBoyIsaiah ?

Answer 7

Yeah I get it

Answer 8

very good.
