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 roots? To find the complex roots of a quadratic equation use the formula: x = (-b±i√ (4ac – b2))/2a WebNow we square both sides of √2 = a/b to get 2=a²/b² and from there it is a short journey to show that since 2=a²/b², it means that both a and b must be even numbers which means they have a 2 in common.
