Quadratic Equations & Inequations Solve x^(4)-2x^(2)-63<=0

A(4,0),B(-4,0) are two points.The locus of P which moves such that |PA-PB|=6 is (i)9x^(2)-7y^(2)+63=0 (ii) 9x^(2)+7y^(2)-63=0( iii) 9x^(2)+7y^(2)+63=0 (iv) 9x^(2)-7y^(2)-63=0

factors of (2x^(2)-3x-2)(2x^(2)-3x)-63 are:

The equation of the hyperbola with centre at the origin the length of transverse axis 6 and one focus is (0,4) is (i) 9x^(2) - 7y^(2) = 63 (ii) 7y^(2) - 9x^(2) = 63 (iii) 9y^(2) - 7x ^(2) = 63 (iv) 7x^(2)-9y^(2)=63

Using the Remainder Theorem, factorise each of the following completely: (i) 3x^3+2x^(2)-19x+6 (ii) 2x^(3)+x^2-13x+6 (iii) 3x^(3)+2x^2-23x-30 (iv) 4x^3+7x^2-36x-63 (v) x^3+x^2-4x-4
