Factorize : 3x^(2)+6xy

Divide: (i) 5m^(2) - 30 m^(2) + 45m by 5m (ii) 8x^(2) y^(2) - 6xy + 10 x^(2) y^(3) by 2xy (iii) 9x^(2) y - 6xy + 12 xy^(2) by - 3xy (iv) 12x^(4) + 8x^(3) - 6x^(2) by -2x^(2)

The sides of a triangle are x^(2) - 3xy + 8, 4x^(2) + 5xy - 3 and 6 - 3x^(2) + 4xy . Find its perimeter.

If 3x^(2)-6xy-by^(2)=0 represents a pair of lines inclined at an angle pi then b=

If the equation 3x^(2)+6xy+my^(2)=0 represents a pair of coincident straight lines, then (3m)/2 is equal to

Subtract: (i) -8xy from 7xy (ii) x^(2) from -3x^(2) (iii) (x - y) from (4y - 5x) (iv) (a^(2) + b^(2) - 2ab) from (a^(2) + b^(2) + 2ab) (v) (x^(2) - y^(2)) from (2x^(2) - 3y^(2) + 6xy) (vi) (x -y + 3z) from (2z - x - 3y)

Factorize: 8x^(3)+y^(3)+12x^(2)y+6xy^(2)
