1. Problem Description

The problem is to find the roots of the quadratic equation x2+9x+14=0x^2 + 9x + 14 = 0.

2. Solution Steps

We need to solve the quadratic equation x2+9x+14=0x^2 + 9x + 14 = 0. We can solve this by factoring. We look for two numbers that multiply to 14 and add to

9. The numbers 2 and 7 satisfy these conditions, since $2 \cdot 7 = 14$ and $2 + 7 = 9$.

Therefore, we can factor the quadratic equation as:
(x+2)(x+7)=0(x+2)(x+7)=0
To find the roots, we set each factor equal to zero:
x+2=0x+2 = 0 or x+7=0x+7 = 0
Solving for xx in each case, we have:
x=2x = -2 or x=7x = -7

3. Final Answer

The solutions to the quadratic equation x2+9x+14=0x^2 + 9x + 14 = 0 are x=2x = -2 and x=7x = -7.
