How do you simplify #-4( 5+ x ) + x + 6#?

Answer 1

Gianna Caruso

#=-14-3x#

#-4(5+x)+x+6#

expand brackets, #=(-4)*5+ (-4)*x+x+6#

#=-20-4x+x+6#

#=-3x-14#

#=-(3x+14)#

you can't factorise so that is the simplest form.

To simplify the expression ( -4(5 + x) + x + 6 ), distribute the -4 to the terms inside the parentheses:

( -4 \times 5 = -20 ) ( -4 \times x = -4x )

Now, rewrite the expression:

( -20 - 4x + x + 6 )

Combine like terms:

( (-20 + 6) + (-4x + x) )

( -14 - 3x )

Therefore, the simplified expression is ( -14 - 3x ).

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.
