What is 3x squared minus x squared?

Answer 1

3x^2 - x^2 = (3 - 1)(x^2) = 2x^2 It is a good idea early one in math to think of things like this.. just like we can add or subtract numbers, we can add or subtracts x^2 or x^3 or squareroots of x... So think of 3x^2 as three (x^2)s...that is to say x^2 is something, like apples or Oranges and you are just taking 3 or them and taking away one of them, so you have 2 of them.

Answer 2

The expression 3x^2 - x^2 simplifies to 2x^2. This is because when you subtract like terms, you subtract the coefficients while keeping the variable and its exponent the same. In this case, the coefficient of x^2 is 3 and 1, so subtracting them gives you 2.

Answer 3

Well, darling, 3x squared minus x squared is simply 2x squared. It's basic math, nothing to lose sleep over. Just remember to watch out for those pesky variables and you'll be golden.

Answer 4

4x2
