# I'm hoping I did thesse right.

(I don't know how to do symbols on here so i'll write it out in word form)
The equation is: x squared + 3x+4=0 I said its not possible because i got x=3 + or - the square root of -7/2 and you cant find a square root of a negative number.

Am I correct?

Have you ever heard of imaginary roots?

i = sqrt (-1)
sqrt(-7) = sqrt(7) i

no. we havent done them. so your saying you can find the square root of a negative number and solve a quadratic equation?

## Yes, you can find the square root of a negative number. In mathematics, we use the concept of imaginary numbers to handle such cases. Imaginary numbers are denoted by the symbol "i," which represents the square root of -1. So, when you have a negative number under the square root, like in the equation x^2 + 3x + 4 = 0, you can express it as √(-7) = √(7)i.

x = (-b ± √(b^2 - 4ac)) / (2a)

Here, a, b, and c are the coefficients of the quadratic equation in the standard form, ax^2 + bx + c = 0.

In your case, the equation is x^2 + 3x + 4 = 0, so a = 1, b = 3, and c = 4. Plugging these values into the quadratic formula:

x = (-(3) ± √((3)^2 - 4(1)(4))) / (2(1))
= (-3 ± √(9 - 16)) / 2
= (-3 ± √(-7)) / 2

Since √(-7) can be expressed as √(7)i, the solution becomes:

x = (-3 ± √(7)i) / 2

Therefore, the correct answer to the quadratic equation x^2 + 3x + 4 = 0 is:

x = (-3 + √(7)i) / 2 and x = (-3 - √(7)i) / 2

These are the two complex conjugate solutions to the equation.
