Question

Simplify 2(3-7i)-i(-4+5i)

Answer 1

Answer:

$- 5i^2 + - 10i + 6$

Step-by-step explanation:

2(3-7i)-i(-4+5i)

$(6 - 14i) + (4i - 5i^2)$

$- 5i^2 - 10i + 6$

you distribute the 2 to the (3-7i) getting 6-14i. then distribute the -i to the (-4+5i) getting 4i-5i^2. then simply combine like terms
