Simplify `lm-(ml-2m)-(lm+2l)-(l-m)+lm`

|[(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)

Factorize (l+m)^(2)-4lm

Factoris the expression. l ^(2) m ^(2) n - lm ^(2) n ^(2) - l^(2) mn ^(2)

If x/(lm-n^2)=y/(mn-l^2)=z/(nl-m^2) , then show that lx+my+nz=0

Simply (x^(m)/x^(n))^(m^(2)+mn+n^(2))xx(x^(n)/x^(l))^(n^(2)+nl+l^(2))xx(x^(l)/x^(m))^(l^(2)+lm+m^(2))

Find the product of the following monomials k^(2)l, lm^(2), km^(2), k^(3)lm

Factories: (l +m)^(2) - 4 lm

If x/(lm - n^2) = y/(mn - l^2) = z/(nl - m^2) the value of lx + my +nz will be

The perfect square form of the quadratic equation lx^(2)+mx+n=0(l""ne0) is (x+(m)/(2l))^(2)=(m^(2)+4lm)/(4l^(2))
