Question

Find the product of the following using some quicker grouping

$-212\times (-36)+(-212)\times (-64)$

Answer 1

Given

$-212\times (-36)+(-212)\times (-64)$

Taking $-212$as common form both the terms we will get

$\Rightarrow$$-212\times (-36)+(-212)\times (-64)$$=-212(-36-64)$

$\Rightarrow$$-212\times (-36)+(-212)\times (-64)$$=-212(-100)$

$\Rightarrow$$-212\times (-36)+(-212)\times (-64)$$=21200$

Hence, the correct answer is $21200$
