3  73/84

 2+3=5                11/84+73/84= 84/84 =1

5+1=6

The polynomial below is NOT in standard form: - 4 + 7x² + 3x Rearrange the terms so that the polynomial is in standard form: Sub
dangina [55]

Answer:

answer maybe x^2 + 3x - 28

explanation

first of all this is how any number of such a kind shud be written

ax^2 + bx + c

so that rearrange it

7x^2 + 3x -4

but I personally would go further to put it like this

x^2 + 3x - 28

both answers are the same so but maybe one is more considered since ur qn requires standard form

in case of any misunderstanding plizzz reach out for further explanation

hope this helps
