1. Problem Description

The problem is to solve the quadratic equation 2x211x+14=02x^2 - 11x + 14 = 0 for xx.

2. Solution Steps

We can solve the quadratic equation 2x211x+14=02x^2 - 11x + 14 = 0 by factoring. We are looking for two numbers that multiply to 214=282 \cdot 14 = 28 and add up to 11-11. These numbers are 4-4 and 7-7. We can rewrite the middle term 11x-11x as 4x7x-4x - 7x. Thus,
2x211x+14=2x24x7x+14=02x^2 - 11x + 14 = 2x^2 - 4x - 7x + 14 = 0.
Now, we factor by grouping:
2x(x2)7(x2)=02x(x - 2) - 7(x - 2) = 0
(2x7)(x2)=0(2x - 7)(x - 2) = 0
To find the solutions, we set each factor equal to zero:
2x7=02x - 7 = 0 or x2=0x - 2 = 0
Solving for xx in each case gives:
2x=7    x=722x = 7 \implies x = \frac{7}{2}
x=2x = 2
Therefore, the solutions are x=72x = \frac{7}{2} and x=2x = 2.

3. Final Answer

x=72,2x = \frac{7}{2}, 2
