WebMultiply both numerator and denominator of \frac{4+4i}{-4+3i} by the complex conjugate of the denominator, -4-3i. Re(\frac{\left(4+4i\right)\left(-4-3i\right)}{\left(-4\right)^{2}-3^{2}i^{2}}) Multiplication can be transformed into difference of squares using the rule: \left(a-b\right)\left(a+b\right)=a^{2}-b^{2}.
