1. Problem Description

We are given the quadratic equation 4x(x1)+17=144x(x-1) + 17 = 14. We need to determine the type of solutions this equation has using the discriminant. We are asked not to solve the equation explicitly.

2. Solution Steps

First, simplify the equation:
4x(x1)+17=144x(x-1) + 17 = 14
4x24x+17=144x^2 - 4x + 17 = 14
4x24x+1714=04x^2 - 4x + 17 - 14 = 0
4x24x+3=04x^2 - 4x + 3 = 0
Now, we have a quadratic equation in the form ax2+bx+c=0ax^2 + bx + c = 0, where a=4a = 4, b=4b = -4, and c=3c = 3.
The discriminant, denoted by Δ\Delta, is given by the formula:
Δ=b24ac\Delta = b^2 - 4ac
Plug in the values of aa, bb, and cc:
Δ=(4)24(4)(3)\Delta = (-4)^2 - 4(4)(3)
Δ=1648\Delta = 16 - 48
Δ=32\Delta = -32
Since the discriminant is negative (Δ<0\Delta < 0), the quadratic equation has two nonreal complex solutions (complex conjugate roots).

3. Final Answer

Two nonreal complex solutions
