Factorize the following expression; 2x2 + x - 15
(2x+5)(x-3)
(2x-5)(x+3)
(2x-5)(x-3)
(2x-3)(x+5)
(2x+5)(x+3)
Correct answer is B
2x 2 + x - 15; 2x 2 + 6x - 5x - 15
(2x 2 + 6x) - ( 5x + 15)
2x(x + 3) - 5(x + 3)
(2x - 5)(x + 3)
The graph above is that of a quadratic function y = 2x2 - x - 6
The roots of the equation are
1.5, 2
-1.5, 2
1, -6
1, 6
-1, 6
Correct answer is B
The roots are; x = -1.5 and 2
Evaluate \(\frac{0.009}{0.012}\), leaving your answer in standard form.
7.5 x 102
7.5 x 101
7.5 x 10-1
7.5 x 10-2
7.5 x 10-3
Correct answer is C
\(\frac{0.009}{0.012}\)
=\(\frac{0.009}{0.012}\) = \(\frac{9}{12}\) = 0.75
=\(7.5 \times 10^{-1}\)
(35-2b)(b-1)
(7+b)(5-b)
(3+7b)(5-b)
(35-b)(3b+7)
(7+b)(5+b)
Correct answer is B
35 - 2b - b 2;
35 - 7b + 5b - b 2
7(5 - b) + 5(5 - b)
(7 + b)(5 - b)
Evaluate, using logarithm tables \(\frac{5.34 \times 67.4}{2.7}\)
1.332
13.32
133.2
1332
13.320
Correct answer is C
| No | Log |
| 5.34 | 0.7275 + |
| 67.4 | 1.8287 |
| 2.5562 - | |
| 2.7 | 0.4314 |
| Antilog = 133.2 | 2.1248 |
\(\therefore \frac{5.34 \times 67.4}{2.7} = 133.2\)
