3.4x(x pangkat dua+2xy-3y pangkat dua)
pakai cara

Answer 1

Verified answer

Jawab:
_________
2x(4x^2 - 3y)

2x (4x^2)+2x(− 3y)

(2 x 4)xx^2 + 2x (-3y)

8xx^2 + 2x (-3y)

8x^1+2 + 2x (-3y)

8x^3 + 2x (-3y)

8x^3 - 6xy

______________________
x (3x+y+5)

x(3x)+xy+x(5)

x^2(3)+xy+x(5)

3x^2+xy+x(5)

3x^2+xy+5x
_______________________
4x(x^2 +2xy -3y^2)

4xx^2+4x(2xy+4x) (-3y^2)

4x^1+2 + 4x(2xy+4x) (-3y^2)

4x^3 + 4x(2xy+4x) (-3y^2)

4x^3(4 x 2)xxy + 4x(-3y2)

4x^3 + 8xxy + 4x(-3y^2)

4x^3 + 8x^2 y + 4x(-3y^2)

4x^3 + 8x^2 y - 12xy^2
