Given that (x − 2) is a factor of f(x) = x² - kx + 4,
the value of k is
4.
0.
-4.
5.
In the expression 3x² - 15x, the common factor is:
3².
3x.
5x.
The graph of the function f(x) = 2x² - 3x - 2 has:
A minimum turning point.
A maximum turning point.
Both maximum and minimum turning points.
No turning point.
The expression x2 - (2x - 3)(2x + 3) when expanded and simplified gives:
-3(3 + x²).
3(3 - x²).
(3 + x)(3 - x).
3(3 + x²).
The equation x(x + 2) - 3(x + 2) has solution(s):
(-3, -2).
(2).
(-3, 2).
(3, -2).
