Question Find the roots Find the roots of the algebra expression a1=−i,a2=i Evaluate a2+1To find the roots of the expression,set the expression equal to 0 a2+1=0Move the constant to the right-hand side and change its sign a2=0−1Removing 0 doesn't change the value,so remove it from the expression a2=−1Take the root of both sides of the equation and remember to use both positive and negative roots a=±−1Simplify the expression a=±iSeparate the equation into 2 possible cases a=ia=−iSolution a1=−i,a2=i Show Solution
