 Hello and welcome to the session. My name is Mansi and I'm going to help you with the following question. The question here says solve each of the following equations. First equation is x squared plus 3 equal to 0. In this question we have to solve the following equation. Now before starting with the solution we see the key idea behind the question. We see that solution to a quadratic equation ax squared plus bx plus c equal to 0 where a is not equal to 0 is given by x is equal to minus b plus minus under the root b squared minus 4ac the whole divided by 2a. This is equal to minus b plus minus under root 4ac minus b squared the whole divided by 2a multiplied by a. Now let us find the solution to this question. It's given to us that x squared plus 3 equals to 0. This implies x squared is equal to minus 3. This implies x is equal to plus minus under the root of minus 3 and this implies x is equal to plus minus root 3 iota. Therefore our solution to this question is plus minus root 3 iota. I hope you understood the question and enjoyed the session. Goodbye.
