1. Problem Description

The problem asks to solve the quadratic equation 2x27x+3=02x^2 - 7x + 3 = 0.

2. Solution Steps

We can solve the quadratic equation 2x27x+3=02x^2 - 7x + 3 = 0 using factoring.
We look for two numbers that multiply to 23=62 \cdot 3 = 6 and add up to 7-7. These numbers are 6-6 and 1-1.
Then we can rewrite the middle term as 7x=6xx-7x = -6x - x.
So, the equation becomes 2x26xx+3=02x^2 - 6x - x + 3 = 0.
Now we factor by grouping:
2x(x3)1(x3)=02x(x - 3) - 1(x - 3) = 0
(2x1)(x3)=0(2x - 1)(x - 3) = 0
Setting each factor equal to zero, we have:
2x1=02x - 1 = 0 or x3=0x - 3 = 0
Solving for xx in each case:
2x=12x = 1 implies x=12x = \frac{1}{2}
x=3x = 3
We can also use the quadratic formula:
For a quadratic equation of the form ax2+bx+c=0ax^2 + bx + c = 0, the solutions are given by:
x=b±b24ac2ax = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}
In our case, a=2a = 2, b=7b = -7, and c=3c = 3.
x=(7)±(7)24(2)(3)2(2)x = \frac{-(-7) \pm \sqrt{(-7)^2 - 4(2)(3)}}{2(2)}
x=7±49244x = \frac{7 \pm \sqrt{49 - 24}}{4}
x=7±254x = \frac{7 \pm \sqrt{25}}{4}
x=7±54x = \frac{7 \pm 5}{4}
So, x=7+54=124=3x = \frac{7 + 5}{4} = \frac{12}{4} = 3 or x=754=24=12x = \frac{7 - 5}{4} = \frac{2}{4} = \frac{1}{2}

3. Final Answer

The solutions are x=12x = \frac{1}{2} and x=3x = 3.
