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:
