Finding real and imaginary roots

WebIf x = 1 then x 2 = 1, but if x = –1 then x 2 = 1 also. Remember that the square of real numbers is never less than 0, so the value of x that solves x 2 = –1 can’t be real. We call it an imaginary number and write i = √ –1. … WebThe roots are the points where the function intercept with the x-axis What are complex roots? Complex roots are the imaginary roots of a function. How do you find complex …

Webx2 − 9 has a degree of 2 (the largest exponent of x is 2), so there are 2 roots. Let us solve it. A root is where it is equal to zero: x2 − 9 = 0. Add 9 to both sides: x2 = +9. Then take the square root of both sides: x = ±3. So the roots are −3 and +3.
