I am new to the expanding stuff can someone give me a detailed explanation to 2x(11x+1)?
multiply every term inside the parentheses by the 2x factor. 2x(11x+1) = 2x*(11x) + 2x(1) = 22x² + 2x
2x(11x+1) = 22x^2 + 2x
It depends upon what you actually mean. Is it meant to be :- 1) (2x) ( 11 x + 1 ) = 22x² + 2x or , is it meant to be :- 2) (2) ( 11 x + 1 ) = 22 x + 2
