[size=150](3x-2) (3x+2) + (x-4) ( 3x-1)[/size]
First expand and simplify both sets of brackets using the FOIL method and cross-multiplying, First, Outer, Inner, Last
First set of brackets :-
First :: 3x * 3x = 9x
Outer :: 3x * 2 = 6x
Inner :: -2 * 3x = -6x
Last :: -2 * 2 = -4
First set of brackets expanded = 9x + 6x - 6x - 4
First set of brackets expanded AND simplified = 9x - 4
Second set of brackets :-
First :: x * 3x = 3x
Outer :: x * -1 = -x
Inner :: -4 * 3x = -12x
Last :: -4 * -1 = 4
First set of brackets expanded = 3x - x - 12x + 4
First set of brackets expanded AND simplified = -10x + 4
Result = (9x - 4) + (-10x + 4)
Answer = -19x
Hope this helped mate.
