1. Problem Description

We are given a quadratic equation 2x2+4x6=02x^2 + 4x - 6 = 0 and we need to find the values of xx that satisfy this equation.

2. Solution Steps

First, we can simplify the equation by dividing all terms by 2:
x2+2x3=0x^2 + 2x - 3 = 0
Next, we can try to factor the quadratic expression. We are looking for two numbers that multiply to -3 and add up to

2. These numbers are 3 and -

1. Thus, we can factor the equation as:

(x+3)(x1)=0(x + 3)(x - 1) = 0
Now, we can set each factor equal to zero and solve for xx:
x+3=0x + 3 = 0 or x1=0x - 1 = 0
Solving for xx in each case gives:
x=3x = -3 or x=1x = 1
Therefore, the solutions to the quadratic equation are x=3x = -3 and x=1x = 1.
Alternatively, we can use the quadratic formula to solve for xx. The quadratic formula is:
x=b±b24ac2ax = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}
For the equation x2+2x3=0x^2 + 2x - 3 = 0, we have a=1a = 1, b=2b = 2, and c=3c = -3. Plugging these values into the quadratic formula, we get:
x=2±224(1)(3)2(1)x = \frac{-2 \pm \sqrt{2^2 - 4(1)(-3)}}{2(1)}
x=2±4+122x = \frac{-2 \pm \sqrt{4 + 12}}{2}
x=2±162x = \frac{-2 \pm \sqrt{16}}{2}
x=2±42x = \frac{-2 \pm 4}{2}
x=2+42x = \frac{-2 + 4}{2} or x=242x = \frac{-2 - 4}{2}
x=22x = \frac{2}{2} or x=62x = \frac{-6}{2}
x=1x = 1 or x=3x = -3

3. Final Answer

The solutions to the equation are x=3x = -3 and x=1x = 1.
