Q. Evaluate the expression (−4+1i)−(2+7i) and write the result in the form a+bi.The real number a equals _____The real number b equals _____
Subtract Real and Imaginary Parts: To evaluate the expression (−4+1i)−(2+7i), we need to subtract the real parts and the imaginary parts separately.Calculation: (−4−2)+(1i−7i)=−6−6i
Calculate Result: Now we have the expression in the form a+bi, where a is the real part and b is the coefficient of the imaginary part.The real number a equals −6.The real number b equals −6.
