I'm hoping I did thesse right.

Solve each quadratic equation.

(I dont 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?
