pre-algebra basics review

when combining like terms, we are adding each term with the same variable and exponent

if two expressions are equivalent then when they are simplified to standard form they are exactly the same.

6\left(x+1\right)+2x in standard form is

which expression is equivalent to 4x+6+5x+2

6x+6+4x in standard form is

when distributing we are multiplying the number in front of a parenthesis to all the terms inside of the parenthesis

Standard form is a state in which an expression cannot be simplified anymore by distribution or combining like terms

which expression is equivalent to 4\left(x+2\right)

6\left(x+1\right) in standard form is
