Question
Find three consecutive odd integers such that the first integer times thesecond integer is one less than four times the third
Solution
Let's denote the three consecutive odd integers as x, x+2, and x+4.
According to the problem, the first integer times the second integer is one less than four times the third. This can be written as:
x*(x+2) = 4*(x+4) - 1
Expanding and simplifying the equation gives:
x^2 + 2x = 4x + 16 - 1
x^2 + 2x - 4x - 15 = 0
x^2 - 2x - 15 = 0
This is a quadratic equation in the form ax^2 + bx + c = 0. We can solve it by factoring:
(x - 5)(x + 3) = 0
Setting each factor equal to zero gives the solutions x = 5 and x = -3.
However, since we're looking for positive odd integers, we discard x = -3.
So, the three consecutive odd integers are 5, 7, and 9.
