What we have done so far is start with a certain number set find an equation with a solution which is not part of that number set and then define a new number set which does include the solution.
Imaginary solution math. This imaginary part i is defined by the property i 2 1 i 2. It seems like we cannot multiply a number by itself to get a negative answer. For imaginary solutions since the graph has no roots it has a discriminant left b 2 4ac right that is less than 0 if it were equal to 0 there d be one solution and if it were greater than zero there d be two solutions. 2 2 4.
The graph will never touch the x axis yet we can still find imaginary roots and the roots will have. Learn about the imaginary unit i about the imaginary numbers and about square roots of negative numbers. An imaginary number is a complex number that can be written in the form of a real number multiplied by an imaginary part named i. Always positive or zero.
As we learned here in the introduction to quadratics section the discriminant can be used to determine what type of solutions a quadratic has. And we can use this method again. I i 1. Let s think about the equation x 2 1.
2 2 4 because a negative times a negative gives a positive 0 0 0. Math algebra 2 complex. 0 1 0 1 0 01.
