Given the equation:
( x - 2 ) ( x + 5 ) = 18
Determine the solution of the equation.
Solution:
In order to determine the solution of the equation we simply equate the factors to 0, then solve for x.
x - 2 = 0
x + 5 = 0
Transpose -2 and 5 to the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.
x = 2
x = -5
Final answer:
x = 2
x = -5
