Question

write 4r+3-9r^2+7r in standard form

Answer 1

Hi Poooooo;

I am not certain what you mean by "standard form", but I will do my best.

 

I believe the equation is...

4r+3-9r²+7r

 

First...

4r+7r=11r

 

The equation is now...

7r+3-9r²

 

I suspect this would be standard, as it is the equation format and typically see...

-9r²+7r+3
