6a^(2)+17ab-3b^(2)

Factorise the following : 3a^(2)+7ab -6b^(2)

Simplify: 4ab(a-b)-6a^(2)(b-b^(2))-3b^(2)(2a^(2)-a)+2ab(b-a)

Simplify : 6a^(2)+3ab+5b^(2)-2ab-b^(2)+2a^(2)+4ab+2b^(2)-a^(2) .

If 6a^(2)+12b^(2)+2c^(2)+17ab-10bc-7ac=0 then all the lines represented by ax+by+c=0 are concurrent at the point

The product (a+b)(a-b)(a^(2)-ab+b^(2))(a^(2)+ab+b^(2)) is equal to: a^(6)+b^(6)(b)a^(6)-b^(6)(c)a^(3)-b^(3)(d)a^(3)+b^(3)

If 9a^(2)-6ab+b^(2)=0 then find a:b

If a^(2) +b^(2) = 13 and ab= 6 find: 3(a+b) ^(2) - 2(a-b)^(2)

If x=2a^(2)+3b^(2)-5ab, y=b^(2)-3a^(2)+7ab and z=6a^(2)-b^(2)+ab , find: x+y-z

If x=2a^(2)+3b^(2)-5ab, y=b^(2)-3a^(2)+7ab and z=6a^(2)-b^(2)+ab , find: x-y+z
