Answer:
4m^4 - 8/3m^2 n^2 + 4/9n^4
Step-by-step explanation:
(2m^2 - 2/3n^2)(2m^2 - 2/3n^2)
= 2m^2(2m^2 - 2/3n^2) - 2/3n^2(2m^2 - 2/3n^2)
= 4m^4 - 4/3m^2 n^2 - 4/3m^2n^2 + 4/9n^4
= 4m^4 - 8/3m^2 n^2 + 4/9n^4
The step where the error occurred is Step 4. After step 3, 34x should've been added to both sides of the equation. Instead of -17x, Step 4 should say 17x, because -17+34=17. Somehow, the whole number in Step 4 also changes from 40 to 14. Nothing changed it, it should still be 40. Step 4 should be: 17x=40.
To continue solving, divide both sides by 17.
x should be 40/17 or 2 6/17.
I hope this helps :)
Answer:
sin2x + 
x + c
Step-by-step explanation:
using the trigonometric identity
• cos² x = (cos2x + 1) and
∫cos ax = 
sin ax
hence
∫(1 - (cos2x + 1)dx
= ∫(1 - cos2x - )dx
= ∫( - cos2x)dx
= x - sin2x + c
where c is the constant of integration
