\[\displaystyle 2(x+1)-3 = 2x + 2 - 3 = 2x - 1\] So as you can see, there is a bit of simplification in this expansion process. So, it is not totally true that expanding is the opposite to simplifying.

To expand the expression 2 (x + 3), we will use the distributive property of multiplication over addition. The distributive property states that for any numbers a, b, and c, the equation a (b + c) = ab + a c holds true. In this case, we can think of 2 as a, x as b, and 3 as c. So applying the distributive property: Multiply 2 by x: 2 × x = 2 x ...
expand(x*(x+2)) returns x*x +x*2; expand((x+3)^2) returns `3^2+2*3*x+x^2` In mathematics, to expand an expression or to expand a product that is transformed into algebraic sum.

To expand the expression 2 (x + 3), we start by using the distributive property. This property states that a (b + c) = ab + a c. In our case, a = 2, b = x, and c = 3. We can expand the expression step-by-step: Distribute 2 to both terms inside the parentheses: First, multiply 2 by x: 2 ⋅ x = 2 x; Next, multiply 2 by 3: 2 ⋅ 3 = 6; Now ...
For example, if you type in x^3 to enter the power x 3, press to return to the base before entering another term (e.g. x 3 +3x). If you don't, then your expression will look like this: x 3+3x . When you press the ( key, both left and right parenthesis are created, and the cursor is placed inside them.
