If x, y, z are integers and x $greater or equal than$ 0, y $greater or equal than$ 1, z $greater or equal than$ 2, x + y + z = 15, then the number of values of the ordered triplet (x, y, z) is -

Let p, q $element of$ {1, 2, 3, 4}. Then number of equation of the form px² + qx + 1 = 0, having real roots, is

Here we used the concept of quadratic equations and solved the problem. We also understood the concept of discriminant and used it in the solution to find the intervals. Therefore, total 7 seven solutions are possible so $7$ equations can be formed.
