Expand and simplify: (x−1)(x3+x2+x). Expand and SimplifyA mathematical expression can be expanded when it involves a multiplication between terms. Mostly the distributive property is used in this type of mathematical expression. Being the distributive property, multiply each term of the f...
simplify(sin(x)^2 + cos(x)^2) simplify(2*(sin(t)^2 + cos(t)^2)) The first sin formula in x and the sin formula in t both simplify to 1 and the overall second expression simplifies to 2. If it were true that expand() is the reverse of simplify then it follows that if you...
