Since there is no condition whatsoever for this arrangement, I can consider the 2 digits and the 5 letters as 7 different objects.
Total permutation (with no repetition):
7 chosen among 7 , that is 7 ! = 5040 arrangements
Total permutation (WITH REPERTITION):
7⁷ = 823 543
The solutions to the quadratic equations are:
a)
b) x = -8, x = 5.
A quadratic function is given according to the following rule:
The solutions are:
In which:
Item a:
The coefficients are a = 5, b = -6, c = -2, hence:
Item b:
The equation is:
x² + 3x = 40
x² + 3x - 40 = 0.
It can be simplified as follows:
(x - 5)(x + 8) = 0.
Hence the solutions are:
