How do you simplify #2(x^2-x) #?

Answer 1

Julia Adams

#2x^2-2x#

#"each term inside the bracket is multiplied by the "2#

#rArrcolor(red)(2)(x^2-x)#

#=(color(red)(2)xx x^2)+(color(red)(2)xx-x)#

#=2x^2-2x#

See a solution process below:

Each term enclosed in parenthesis is multiplied by the term outside the parenthesis;

#color(red)(2)(x^2 - x) =>#

#(color(red)(2) xx x^2) - (color(red)(2) xx x) =>#

#2x^2 - 2x#

Genesis Allen

To simplify ( 2(x^2 - x) ), distribute the 2 across the terms inside the parentheses:

[ 2(x^2 - x) = 2 \times x^2 - 2 \times x ]

[ = 2x^2 - 2x ]

So, ( 2(x^2 - x) ) simplifies to ( 2x^2 - 2x ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
