Question

need the answer to (2x-y)(4x²+2xy+y²)

Answer 1

Answer:

Step-by-step explanation:

1 - Directly Multiply the given values of both the brackets.

---First lets multiply the 2x with the whole equation of 2nd bracket.

It implies --- 2x*4x^2+2xy+y^2.

= 8x^3+4x^2y+2xy^2.------- equ (1)

---Now lets multiply the term -y with the whole equation of 2nd bracket.

It implies --- (-y)*4x^2+2xy+y^2.

= (-4x^2y-2xy^2-y^3).------ equ (2)

Now we have multiplied the both equations with each other .

2 - Now solve both the equations.

=8x^3+4x^2y+2xy^2-4x^2y-2xy^2-y^3.

⇔ 8x^3-y^3.
