The mistake he did, was in calculating powers, when 12 is taken to numerator it becomes -12 and 6-12 is -6 and not 6 so power of x should be -6 i.e x^-6 and not x^6
So, the correct answer is
Step-by-step explanation:
We need to simplify:
Solving:
Multiplying power with the terms inside the bracket.
Now combining powers of same variable i.e if
Solving:
The exponent rule says: if

Answer:
17 - i
Step-by-step explanation:
<u>Step 1: FOIL out</u>
(1 - 3i)(2 + 5i)
(2) + (1 * 5i) + (-3i * 2) + (-3i * 5i)
2 + 5i - 6i - 15i^2
2 - i + 15
<em>17 - i</em>
