Most Upvoted Answer
Find x with quadratic formula x^2+4x+5=?
Solving for x using the quadratic formula:
1. Identifying coefficients:
The given quadratic equation is x^2 + 4x + 5. Here, the coefficients are a=1, b=4, and c=5.
2. Using the quadratic formula:
The quadratic formula is x = (-b ± √(b^2 - 4ac)) / 2a.
Substitute the values of a, b, and c into the formula to solve for x:
x = (-4 ± √(4^2 - 4*1*5)) / 2*1
x = (-4 ± √(16 - 20)) / 2
x = (-4 ± √(-4)) / 2
x = (-4 ± 2i) / 2
3. Calculating the roots:
The roots of the equation x^2 + 4x + 5 are complex numbers:
x = (-4 + 2i) / 2 = -2 + i
x = (-4 - 2i) / 2 = -2 - i
4. Final answer:
The solutions to the quadratic equation x^2 + 4x + 5 are x = -2 + i and x = -2 - i.
