Fractorise:
`(l+m) ^(2) -(l -m)^(2)`

Factorise : (l + m)^2 - (l - m)^2

Factorise : (l + m)^2 – (l – m)^2

Factorize: (l+m)^2-(l-m)^2

Fractorise the following 10 m ^(2) - 31m - 132

Write the greatest common factor in each of the term. l ^(2) m ^(2) n, l m ^(2) n ^(2) , l ^(2) mn ^(2)

|[(m+n)^(2), l^(2), mn], [(n+l)^(2), m^(2), ln], [(l+m)^(2), n^(2), lm]| =(l^(2) +m^(2) +n^(2))(l-m)(m-n)(n-l)(l+m+n)

The coordinates of the mid-point of the line segment joining the points (l, 2m) and (-l +2m, 2l -2m) are

If 2y + (1)/(2y) = l and 2y - (1)/(2y) = m , then l^(2) - m^(2) = "______" .

Find the value of int_(-l/2)^(+l/2)M/l x^(2) dx where M and l are constants .
