Take suitable number of cards given in the adjoining diagram [G`(x xx x)` representing `x^2`, R `(x xx 1)` representing x and Y `(1 xx 1)` representing 1] to factorise the following expressions, by arranging the cards in the form of rectangles: (i) `2x^2 + 6x + 4` (ii) `x^2 + 4x + 4`. Factorise `2x^2 + 6x + 4` by using the figure.
