28. Simplify ( 3 V5 -5 2V5 ) ( 4 V2 + 3 V2)

29. Find p(0), p(1), p(-2) for the following polynomialp(y) = (y + 2)(y-2).

30. Points A (5, 3), B (-2, 3) and D (5,- 4) are three vertices of a square ABCD. Plot

these points on a graph paper and hence find the coordinates of the vertex C.

31. For what value of c, the linear equation 2x + cy = 8 has equal values of x and y

for its solution.

32. Draw the graph of the linear equation 3x + 4y = 6. At what points, the graph cuts

the x-axis and the y-axis.
