because 7 can only be divided by 7 once
Mehek14
  • Mehek14
yes like this \(\dfrac{7x^3}{7x^2}\)
Mehek14
  • Mehek14
correct so 7/7 = 1 how about \(\dfrac{x^3}{x^2}\)
anonymous
  • anonymous
Think it's just x
Mehek14
  • Mehek14
correct
Mehek14
  • Mehek14
now \(\dfrac{42x^2}{7x^2}\)

  • anonymous
Is it 6, 6+x = 6x @Mehek14
Mehek14
  • Mehek14
so the length is \(x+6\)
anonymous
  • anonymous
Okay had it written wrong Thanks Mehek14
Mehek14
  • Mehek14
\((7x^2)(x+6) = 7x^3 + 42x^2\)
Mehek14
  • Mehek14
wait it's -6
anonymous
  • anonymous
Oh? how did it get negative?
Mehek14
  • Mehek14
\(7x^2*(x-6)=7x^3-42x^2\)
Mehek14
  • Mehek14
because -42/7 = -6
anonymous
  • anonymous
Oh, didn't notice the 42 was negative i would of been way off
Mehek14
  • Mehek14
