Dude, I answered your last question...
Except I wrote a bit more...
Look, this is what I answered:
"Here you go!
I hope you understand...
Step-by-step explanation:
a. x(3x² - 2y²)+y (3x²-2y²)
=3x³- 2xy² + 3x²y - 2y³
b. (x²-y²) (x²+y²). { Formula: [ a+b] [a-b] = a²-b²}
= (x²) ² - (y²) ²
= x⁴ - y⁴
d. (x⁴-y⁴) (x+y)
=x(x⁴-y⁴) +y(x⁴-y⁴)
= x power 5 - y⁴x + x⁴y - y power 5
e. (½x-y)(3/5x+y)
= 3/5x(1/2x-y) + y(1/2x-y)
= 3/10x² - 3/5y + ½xy- y²
:D
You're welcome!!
By the way, I couldn't see the 'c. ' one. That's why I skipped it."
