3x - 4
3x + 4
3x +19

Find the sum and choose the correct answer.
2n 3 + 4n 2 - 7 and -n 3 - 8n - 2
-n3 + 4n2 - 8n - 9
n3 + 4n2 - 8n - 9
n3 + 4n2 - 8n - 5
n3 - 4n2 -9


Factor 2x 2 - 10x - 12.
2(x + 2)(x - 3)
2(x - 1)(x + 6)
2(x - 6)(x + 1

Find the quotient.
(4ab - 8a 2 + 12ac) ÷ 4a
b - 2a2 + 3c
b - 2a + 3c
abc

Answer 1

3x + 4
2x + 5|6x² + 23x + 20
6x² + 15x
8x + 20
8x + 20
0
The answer is B.

(2n³ + 4n² - 7) + (-n³ - 8n - 2)
(2n³ - n³) + 4n² - 8n - 7 - 2
n³ + 4n² - 8n - 9
The answer is B.

2x² - 10x - 12
2(x²) - 2(5x) - 2(6)
2(x² - 5x - 6)
2(x² - 3x - 2x - 6)
2(x(x) - x(3) - 2(x) - 2(3))
2(x(x - 3) - 2(x - 3))
2(x - 2)(x - 3)
The answer is A.

4ab - 8a² + 12ac = 4ab - 8a² + 12ac = b - 2a + 3c
4a 4a 4a 4a
The answer is B.
