Question

plz help me in this ​

Answer 1

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.
