Question

25 poin,,...!!!!

Tentukan faktor dari

1.6x-2×^2
2. X^2-25
3. X^2-2x-8
4. X^2+2x-24

Tolong pakai caranya dan jangan ngasal.. thanks :)

Answer 1

1.:
6x - 2x²
2x ( 3 - x)

2.:
x² - 25
x² - 5²
(x -5) ( x + 5)

3.:
x² - 2x - 8
(x² +2x) (-4x - 8)
x(x + 2) - 4 ( x + 2)
(x + 2) ( x -4)

4.:
x² + 2x - 24
(x² - 4x) (6x - 24)
x(x -4) + 6 ( x - 4)
(x - 4) ( x + 6)

Answer 2

1) 6x - 2x² = 2x (3 - x)
2) x² - 25 = (x - 5) (x + 5)
3) x² - 2x - 8 = (x - 4) (x + 2)
4) x² + 2x - 24 = (x - 4) (x + 6)
