The inequality of p^{2 }+ 5 < 5p + 14 can be satisfied if:
Consider the equation:
x5^{2} + 5 x  5  24 = 0
The sum of all the real roots of the above equationis:
Consider the function f(x) = (x + 4)(x + 6)(x + 8) ⋯ (x + 98). The number of integers x for which f(x) < 0 is:
If 2 ≤ x – 1 × y + 3 ≤ 5 and both x and y are negative integers, find the number of possible combinations of x and y.
