4a^(2)-9b^(2)

Simplify each of the products: ((1)/(2)a-3b)(3b+(1)/(2)a)((1)/(4)a^(2)+9b^(2))

If a^(2)+4b^(2)-9c^(2)=4ab , then the line on which is meet the point of concurrency of family of straight line ax+by+3c=0 lies is

If a^(2)+4b^(2)-9c^(2)=4ab, then the line on which the point of concurrency of family of straight line ax+by+3c=0 lies is (a)x+y=-1(c)x+y3(b)x+y=1 (d) 2x+y=0

Add the algebraic expressions: 3a^(2)b,-4a^(2)b,9a^(2)b

If x^(2)+y^(2)=4 and a^(2)+b^(2)=9 then

If x^(2)+y^(2)=4 and a^(2)+b^(2)=9 then

Factorize: (a^(4)-8a^(2)b^(2)+16b^(4))-256a^(4)-6a^(2)b^(2)+9b^(4)-81

Find the square root of : 4 a ^(2) + 9b ^(2) + c ^(2) - 12 ab + 6 bc - 4 ac
