1. Problem Description

The problem is to solve the quadratic equation 2x2+4x6=02x^2 + 4x - 6 = 0.

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 factor the quadratic expression:
We are looking for two numbers that multiply to -3 and add up to

2. Those numbers are 3 and -

1.
(x+3)(x1)=0(x + 3)(x - 1) = 0
Now, we set each factor to zero and solve for xx:
x+3=0x + 3 = 0 or x1=0x - 1 = 0
x=3x = -3 or x=1x = 1
Alternatively, we can use the quadratic formula:
x=b±b24ac2ax = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}
For the simplified equation x2+2x3=0x^2 + 2x - 3 = 0, a=1a = 1, b=2b = 2, and c=3c = -3.
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 are x=1x = 1 and x=3x = -3.
