Solve the following equation:
2x2+4x+1=0
To solve the quadratic equation 2x2+4x+1=0, follow these steps:
- Step 1: Convert to Standard Form
Begin by eliminating the fractions to simplify. Multiply the entire equation by 4, the least common multiple of the denominators:
4(2x2+4x+1)=4⋅0
which simplifies to:
2x2+x+4=0
Now, it's in standard quadratic form: ax2+bx+c=0, with a=2, b=1, and c=4.
- Step 2: Evaluate the Discriminant
The discriminant of a quadratic equation ax2+bx+c=0 is calculated as:
b2−4ac
Substituting the values, we have:
12−4⋅2⋅4=1−32=−31
Since the discriminant is negative, it indicates that there are no real solutions for the equation.
Conclusion: The given quadratic equation has no real solutions due to the negative discriminant.
The correct answer to the problem is therefore, No solution.
