Question

8 Verify the following.

(i) 185 + [(-3) (18xY) +(18 X (-3)]

Answer

$\bf\rm{185 + ( - 3x)(18xy) + 18x - 3}$

$\leadsto\bf\rm{185 + ( - 54xy) + 18x - 3}$

$\leadsto \bf\rm{185 - 3 - 54xy+ 18x }$

$\leadsto\bf\rm{182 - 54xy+ 18x }$

$\leadsto \bf\rm{18x - 54xy + 182 }$

Dividing each term by two,we get.

${ \color{maroon}\leadsto \bf\rm {\color{navy}{9x - 27xy + 91 }}}$

The polynomial is 9x - 27xy + 91

For solving such questions, the principle of BODMAS must be followed where,

B-BRACKET

O-OFF

D-DIVISION

M-MULTIPLICATION

A-ADDITION

S-SUBTRACTION

In the equation $\bf\rm {\color{navy}{9x - 27xy + 91 }}$~ the coefficient are 9,27 and 91, whereas the variable are x and y
