Unfortunately, I do have a SMALL question, that could actually impact the whole thing... it's abt the "(i)"... is it just a part of the 1st question, or does it signify an imaginary unit? I'll solve for both cases.
Answer:
If the "i" is just a subsection of the 1st question, then: 25a²+ 60ab+36b²
If the "i" signifies imaginary numbers, then: 25ia²+ 60iab+36ib²
Step-by-step explanation:
We can use the (a+b)² identity to solve for this problem.
(a+b)² is equivalent to a²+2ab+b².
For us, our "a" is really "5a" and our "b" is "6b".
Substituting, we get:
25a²+ 60ab+36b²
Now, if the "i" signifies imaginary units, then we just have to multiply the expression with "i"!
Doing so, we would get:
25ia²+ 60iab+36ib²
Again, I didn't understand wether or not the "i" was a subsection or an imaginary unit, so I put down both answers.
