  1. Distribute the -2 across the quantity, which means to multiply each term in the parentheses (7a and -2) by -2.

    -2 X 7a = -14a

    -2 X(-2) = 4

    So, the answer is -14a + 4. If you want the first term to be positive, you can multiply both terms by -1 and get this answer, which is also acceptable: 14a -4

    Both answers are algebraically correct.


  2. before i tell you how to solve the problem, if you have future math problem go to think link.

    okay, now lets solve this problem which is very easy. this problem signifies multipication. you can tell because these 2 numbers are next to each other.

    -2(7a-2)

    there are 2 things you are going to multiply. the numbers are 2 7a -2

    1. multiply the negative 2 to the 7a. lets pretend the varible a is 3. so were looking at the numbers: 2, 3, and 7. now no matter what order you multiply these numbers the answer is always going to be the same. ( 42 )

    so multiply the negative 2 to both numbers.

    -2 x 7a is -14a.

    now.........................

    -2 x -2= 4. ( positive 4 )

    so the answer is -14a+4. this is all you can solve, so this is the answer. so distributive property is when you multiply an outside number to numbers in the parenthesis.


  3. -2(7a-2)

    Distribute:

    -2(7a) = -14a

    and

    -2(-2) = 4 (negative x negative = positive)

    Simplify: -14a + 4

  4. Distributive property - you get rid of the parenthesis

    what you do is multiply the -2 by everything inside the parenthesis and then that's it

    did you want the answer?

  5. -2(7a-2)

    multiply -2 to both terms inside the parenthesis

    -14a + 4

  6. -14a + 4.
