Question

State whether the statement is True or False.
Product of $(kl+lm)$ and $(k-l)$ is equal to $k^{2}l-k{l}^2+l^{2}m-klm$

• A. True
• B. False

Answer 1

The correct option is B False

Product of $(kl+lm)$ and $(k-l)$ is ,

$(kl+lm)\times (k-l)=kl(k-l)+lm(k-l)=k^{2}l-k{l}^2+klm-l^{2}m$

Clearly $k^{2}l-k{l}^2+klm-l^{2}m\ne k^{2}l-k{l}^2-klm+l^{2}m$

Hence, The given statement is false.
