123. Take suitable number of cards given in the adjoining diagram [G(x × x) representing x^2, R (x × 1) representing x and Y (1 × 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.
