Find the error in the multiplication. \large \left(x+4i\right)\cdot\left(x-4i\right) Line 1 \large x\cdot x^{ }-4i\cdot x+4i\cdot x+4i\cdot-4i Line 2 \large x^2-4ix+4ix-16i^2 Line 3 \large x^2-16i^2 Line 4 \large x^2-16\cdot-1 Line 5 \large x^2-16 a Line 1 should be \large -4i\cdot-4i at the end of the line b Line 3 should be \large x^2-8i-16i^2 c Line 5 should be \large x^2+16 d Line 2 should be \large x^2-4i-4i-16i^2 e Line 4 should be \large x^2-16\cdot\sqrt{-1}
