Question

Faktorkanlah bentuk-bentuk aljabar berikut. 1. 2x2+7x+3 =
2. 2x2+5x+3 =
3. 3y2+8y+4 =
4. 5x2+13x+6 =
5. 3y2-8y+4 =
6. 8p2-14p+5 =
7. 18m2-8m+1 =
8. 10a2-43a+12 =
9. 12x2-34x+10 =

Answer 1

jwb :

1) 2x² + 7x + 3 = (2x + 1)(x + 3)
2. 2x²+5x+3 = (2x + 3)(x + 1)
3. 3y²+8y+4 = (3y + 2)(y + 2)
4. 5x²+13x+6 = (5x + 3)(x + 2)
5. 3y²-8y+4 = (3y - 2)(y - 2)
6. 8p²-14p+5 = (4p - 5)(2p - 1)
7. 18m²-8m+1 = prima
8. 10a²-43a+12 = (10a - 3)(a - 4)
9. 12x²-34x+10 = (6x - 2)(2x - 5)

semoga membantu :)

Answer 2

2x² + 7x + 3
2x² + 6x + x + 3
2x(x + 3) + 1(x + 3)
(2x + 1)(x + 3)

2x² + 5x + 3
2x² + 2x + 3x + 3
2x(x + 1) + 3(x + 1)
(2x + 3)(x + 1)

3y² + 8y + 4
3y² + 6y + 2y + 4
3y(y + 2) + 2(y + 2)
(3y + 2)(y + 2)

5x² + 13x + 6
5x² + 10x + 3x + 6
5x(x + 2) + 3(x + 2)
(5x + 3)(x + 2)

3y² - 8y + 4
3y² - 6y - 2y + 4
3y(y - 2) - 2(y - 2)
(3y - 2)(y - 2)

8p² - 14p + 5
8p² - 4p - 10p + 5
4p(2p - 1) - 5(2p - 1)
(4p - 5)(2p - 1)

18m² - 8m + 1
tidak ada faktornya

10a² - 43a + 12
10a - 40a - 3a + 12
10a(1 - 4) - 3(a - 4)
(10a - 3)(a - 4)

12x² - 34x + 10
12x² - 30x - 4x + 10
6x(2x - 5) - 2(2x - 5)
(6x - 2)(2x - 5)
