Answer 1

$\Large\sf{\underline{\underline{Question:-}}}$

Simplify:-

3x + 5y [{ 4x - (2x + 5y - 7)} + 2x]

$\Large\sf{\underline{\underline{Solution:-}}}$

3x + 5y [{ 4x - (2x + 5y - 7)} + 2x]

According to BODMAS,

= 3x + 5y [{ 4x - 2x - 5y + 7 } + 2x ]

= 3x + 5y [ 2x - 5y + 7 + 2x ]

= 3x + 5y [ 4x - 5y + 7 ]

= 12x² - 15xy + 21x + 20xy - 25y² + 35y

= 12x² - 25y² + 5xy + 21x + 35y

Hence simplified ✓

Answer 2

$\huge\underbrace\mathcal\purple{Question:-}$

Simplify:

3x + 5y [{ 4x - (2x + 5y - 7)} + 2x]

$\huge\boxed{\fcolorbox{cyan}{green}{Solution:}}$

3x + 5y [{ 4x - (2x + 5y - 7)} + 2x]

According to the rule of BODMAS, we have

= 3x + 5y [{ 4x - 2x - 5y + 7 } + 2x ]

= 3x + 5y [ 2x - 5y + 7 + 2x ]

= 3x + 5y [ 4x - 5y + 7 ]

= 12x² - 15xy + 21x + 20xy - 25y² + 35y

= 12x² - 25y² + 5xy + 21x + 35y
