## Bananas1234 one year ago solve each equation. Write irrational numbers in simplest radical form. Describe the strategy you used to get your solution and tell why you chose that strategy. 1. x^2 + 4 = 0 2. x^2 - 6x + 1 = 0 I think i got number 1. But i need help on question # 2

How did you work out number 1? Just to be sure... For number two you should use the following algorithm: You have to reform the equation to an equation in like: $ax^2+bx+c=0$ With a, b and c real numbers. Then you should determine your determinator $D = b^2-4ac$ And the solutions are: $x_{1} = \frac{ -b+\sqrt{D} }{ 2a }$ $x_{2} = \frac{ -b-\sqrt{D} }{ 2a }$
