We were asked to perform the function indicated and simplify the answer.
(2x^2-5y)^2. My answer was 4x^4-20x^2y+25y. If it is correct am I able to simplify it further? Thank you in advance.
how do you remove brackets? e.g. 2(x+5) or a(a-4)
multiply out of brackets and simplify? e.g. (x+3)(+2) or (2c-3)(3c+4)
