The expression x - 3 is simply (3 - x) multipled by -1
Simply put, an expression does not need an equal sign, while an equation does. Equation: x+y=z Expression: x+y
It factors into (x-3)(x+3) as it follows the difference of squares rule. However, since you gave me an expression and not an equation, I cannot solve this expression beyond this point. If x^2-9=0. Then you can see that (x-3)=0 and (x+3)=0. Thus x=-3, 3.
It depends what "x" is. ======== An algebraic expression representing the difference (subtraction) between 6 and some unknown number (represented by x).
X = 15 - 5y
3 - x = -(x - 3) x - 3 = -(x - 3)
The expression x - 3 is simply (3 - x) multipled by -1
Equation: x+3=3+x (notice the equal sign: equal; equation)Expression: x+3 (notice no equal sign)
Equation: x+3=3+x (notice the equal sign: equal; equation)Expression: x+3 (notice no equal sign)
it has to have an x number in it.
Four times X plus 3 equals seven. 4X + 3 = 7 That!
X - 25or25 - X
the difference between a number and 3 is
Simply put, an expression does not need an equal sign, while an equation does. Equation: x+y=z Expression: x+y
This is a difference of two square, so you can apply the factoring rule for the difference of two squares.
An expression does not include an equals sign (=) For eg: 2x+3 would not be an equation but an expression However, 2x+3=0, is definitely an equation with a solution x= -3/2. An expression does not have a definite solution. An expression is a set of terms with mathematical operations combining them. An equation consists of two expressions with an equals sign between them. An expression is a collection of terms and does not have an = sign An equation is a collection of terms but has an = sign between them.
