" 3.(a) "x^(2)+7x+12

Find the GCD of 3x^(2) - 48 and x^(2) - 7x +12

Solve the following inequalities. (a) |2x-3| lt 1, (b) (x-2)^(2) ge 4 , (c) x^(2) ge 4 , (c) x^(2)+2x-8 le 0 , (d) |x^(2) -7x+12| gt x^(2)-7x+12 .

Factorise the following : (i) x^(2)+7x+12 " " (ii) x^(2)+18x+45 " " (iii) x^(2)-7x+12 " "(iv) x^(2)-25x-84

A common factor of x^(4) -256, x^(3)-4x^(2)+3x-12 and x^(2) -7x+12 is

A common factor of x ^(4) - 256, x ^(3) - 4x ^(2) + 3x - 12 and x ^(2) - 7x + 12 is

The largest integral value of k for which the equation (x-1)(x-2)(x-3)(x-4)+k=0 has real roots is a root of the equation (a) x^(2)-3x+2=0 (b) x^(2)+3x+2=0 (c) x^(2)-7x+12=0(d)x^(2)+7x+12=0

Is {x : x^(2) - 7x + 12=0} = {3,4} ?
