: Hello. A square has sides of length 3x-2 cm. Express the area of the square as a polynomial.
I think it is supposed to be like this, can you check my work and let me know if it correct, or if not where I went wrong?
(3x-2)^2
=3x^2 - 2(3x)(2)+2^2
=9x-12x+4
Is this correct? This question is from textbook Beginning Algebra
