Question

Donte simplified the expression below.4(1+3i) -(8-5i)4+3i-8+5i;-4+8iWhat mistake did Donte make?O He did not apply the distributive property correctly for 4(1 + 31).O He did not distribute the subtraction sign correctly for 8-5.O He added the real number and coefficient of iin 4(1 + 31).O He added the two complex numbers instead of subtracted.

Answer 1

We have to identidy the mistake in the calculation.

We can see that in the second step and the first term, the distributive property is not applied correctly. The result should have been:

$4(1+3i)=4+12i$

differently for the result obtained by Donte.

Answer:

He did not apply the distributive property correctly forr 4(1 + 3i). [First option]
