3(7a - 5b) + 2(4a - 3b)

Multiply the contents of each bracket by the number outside it:

21a - 15b + 8a - 6b

Bring like terms together:

21a + 8a - 15b - 6b

Combine like terms:

29a - 21b

This cannot be simplified further.

7(a + 3) = 7*a + 7*3 = 7a + 21

(a + 5) (a - 5) = a2 - 25

To expand an equation you multiply the number outside the bracket with everything inside the bracket. ex. 3(x+3) becomes 3x+9

You expand the parenthesis out first. Then simplify the rest.

To expand three brackets, expand and simplify two of the brackets then multiply the resulting expression by the third bracket. (FAIZAN BHAI GHAZI)CHANNEL

expanding bracket is basically multiplying and is used in algebra for example: 2(6x+7x) You multiply everything outstide the bracket with everything inside the bracket for example: 2 x 6x=12x 2 x 7x= 14x so now you have expanded the brackets it looks like: 12x + 14x now simplify to make 26x . And that is how to expand brackets

( )( ) -> ( )( ) -> ( )( )

You need to get rid of the brackets first and then simplify it from there. Hope i helped
