what is 4(x+3) (expanded algebra)

Question

Expand these brackets 

4(x+3)

Answer 1

For any numbers:

a(b+c) = a(b) + a(c)

Just multiply the number outside the parenthesis

by each number inside and then add.

 

Example:  5(2+6) = 5(2)+5(6)= 10+30=40

Note this is the same as 5(8) = 40

 

With variables such as your problem the steps

are sthe same

 

6(x-3) = 6(x) + 6(-3) = 6x - 18

 

x(y+7) = x(y) + x(7) = xy + 7x

 

and so forth.

 

4(x+3)

What do you have if you multiply

4(x) + 4(3) ?
