Question

Solve the problem what is (4r3 + 3r4) - (r4 + 5r3)

Answer 1

First you can also remove parenthesis first.

And it gave us ⇒ $4r*3+3r*4-(r*4+5r*3)$, $4r*3=12r$,$3r*4=12r$, $-(r*4+5r*3)=-19r$, and $=12r+12r-19r$.

Finally, you add similar elements.

And it gave us ⇒ $12r+12r-19r=5r$.

Final answer is ⇒ $\boxed{=5r}$

Hope this helps!

Answer 2

Hey there!!

Given:

... 4r³ + 3r⁴ - ( r⁴ + 5r³ )

Let's write this equation as ...

... 4r³ + 3r⁴ -1 ( r⁴ + 5r³ )

Using the distributive property:

... 4r³ + 3r⁴ -1(r⁴) + (-1)(5r³)

... 4r³ + 3r⁴ - r⁴ - 5r³

Combining the like terms:

... 4r³-5r³-r⁴+3r⁴

... 2r²-r³ Is the answer.

Hope my answer helps!
