The remainder when x² - 2x + 7 is divided by (x + 4) is:
15
-1
31
-17
The expansion of (x - 3)(x + 4) is:
x² + x - 12.
x² − x − 12.
x² + x − 7.
x² + x + 1.
The number of factors in the expression (x + 1)(x + 2) is:
1.
2.
3.
4.
The expression x2 - (2x - 3)(2x + 3) when expanded and simplified gives:
3(3 + x²).
(3 + x)(3 - x).
-3(3 + x²).
3(3 - x²).
The equation x(x + 2) - 3(x + 2) has solution(s):
