If 9+2(3x-xy+x^(2))+y^(2)=0 ,then what is the value of (3x^(2)-2xy+5y^(2)) ?

Multiply : 3x^(2) y - 7xy^(2) +2xy" by " 4xy

If the pairs of lines x^(2)+2xy+ay^(2)=0 and ax^(2)+2xy+y^(2)=0 have exactly one line in common,then the joint equation of the other two lines is given by 3x^(2)+8xy-3y^(2)=03x^(2)+10xy+3y^(2)=0y^(2)+2xy-3x^(2)=0x^(2)+2xy-3y^(2)=0

Subtract : 5x^(2)-3xy -7y^(2) from 3x^(2)-xy-2y^(2)

Add 2x^(2)+5xy-2y^(2), 3x^(2)-2xy+5y^(2) and 2x^(2)+8xy+3y^(2)

Add the following expressions using horizontal method : -x^(2)y + xy^(2) + 2xy , 3x^(2) y + 4xy^(2) + 5xy and 7x^(2)y - 10xy^(2) - xy

Subtract the second polynomial from the first : 3x^(2)y-7xy^(2) +5xy, 2xy-x^(2)y +7xy^(2)

Subtract the second polynomial from the first : 3x^(2)y-7xy^(2) +5xy, 2xy-x^(2)y +7xy^(2)

Simplify: 2x^(2)+3xy -3y^(2)+x^(2)-xy+y^(2)
