Factorise (i) x^(2)+9x+18 (ii) 6x^(2)+7x-3 (iii) 2x^(2)-7x-15 (iv) 84-2r-2r^(2)

Reduce (3x^(2) - 11 x- 4)/(6x^(2) - 7x - 3) to its lowest terms.

Which of the following equations has 2 as a root? (a) x^(2)-4x+5=0 , (b) x^(2)+3x-12=0 (c) 2x^(2)-7x+6=0 , (d) 3x^(2)-6x-2=0

The root of x^(3) - 6x^(2) + 7x + 2 = 0 one root being 2 + sqrt(5) are

A: The equation whose roots are the reciprocals of the roots of 2x^(3) + 7x^(2) - 6x + 1 = 0 is x^(3) - 6x^(2) + 7x + 2 =0 . R: the equation whose roots are the reciprocals of those of f(x) = 0 is f(1/x) = 0.
