This question was reportedly attempted by majority of the candidates and they performed well in it. They were able to show that if a and b are the roots, a + b = - and ab = - . An equation whose new roots are (() can be formed by finding the sum ( + ) and products ()(). These were respectively - and .
Therefore the new equation = + + = 0 º 15x2 + 34x + 18 = 0.
