Question 10

(a) If a and {3 are the roots of the equation 2x2 + 5x - 6 = O. find the equation whose roots are (a - 2) and ({3 - 2).

(b)Given the fok(x2- 2x)dx = ~, find the values of k.

Observation

Question 10{a) was very popular among the candidates and they gave a good account of themselves. They were able to write the sum of the roots of the new equation as sum of the
,
roots of the old minus 4, and the product of the new equation as product of old roots - 2{sum of
old roots) + 4 which gave 6; hence obtaining the new equation 2x2 + 13x + 12 = O.
