Question

Please I need help answering this
Which of the following polynomials are in standard form?

x^2 + 3x + 2 <--- I think this one

q^3 – 15q + 12q^2 – 16

4a + a^2 + a – 2 <-- I think this one

3x^4 + 4x^3 – 3x^2 – 1

3t^3 + 3t^2 + 2t <-- I think this one

14 + a^3 – 6a + 8a^2

Answer 1

I think standard form would be in descending order, your first one would be correct
your second would not, since it goes power of 1, power of 2, power of 1, power of 0

you would have to go in descending order which means highest power first, then second highest, then third highest

your third is correct

Answer 2

how does the first one go in power of 1 to power of 2 to power of 1?

Answer 3

your first one is correct, the second one is what I said is in the wrong power order

Answer 4

for example

\[ax^{3}+bx^{2}+cx+d\]

this goes power 3, power 2, power 1, power 0, of x (or whatever variable you use)
this is standard form

Answer 5

Is there any other ones that are in standard form other than the two?

Answer 6

3x^4 + 4x^3 – 3x^2 – 1 this one?

Answer 7

3x^4 + 4x^3 – 3x^2 – 1

this one is standard form since the power starts at the highest number and decreases by one each time

Answer 8

you had 2 right

4a + a^2 + a – 2 this one is wrong

Answer 9

3x^4 + 4x^3 – 3x^2 – 1

so the two that you got right, and this one is your answer

Answer 10

so the last one is wrong because it goes from 3 to 1 to 2?

Answer 11

this one 14 + a^3 – 6a + 8a^2

Answer 12

yeah taht would not be right, since it goes 0,3,1,2

Answer 13

okay thank you

Answer 14

Can you help me with another one?
