Question

Plzzzz help me out its urgent​

Answer 1

Expression Given :-

• $:\mapsto\rm{3x (4x - 5) + 3}$

• We have to simplify the Expression and then find the value of x .
• By putting the value of x as 3
• By putting the value of x as 12

✭Now let's Solve !

★Simplifying :-

$:\leadsto\tt{3x (4x - 5) + 3}$

$:\leadsto\tt{3x\times4x - 3x \times5 + 3}$

$:\leadsto\tt{12x^2 - 15x + 3}$

✴Step 1 :-

• Soluting by putting the value of x as 3

$:\implies\rm{12x^2 - 15x + 3}$

$:\implies\rm{12(3)^2- 15(3) + 3}$

$:\implies\rm{12(3\times3) - 15 × 3 + 3}$

$:\implies\rm{12\times9 - 45+3}$

$:\implies\rm{108-45+3}$

$:\implies\rm{108+3-45}$

$:\implies\rm{111-45}$

$:\implies\rm{66}$

✴Step 2 :-

• Soluting by putting the value of x as 12

$:\implies\rm{12x^2 - 15x + 3}$

$:\implies\rm{12(12)^2 - 15(12) + 3}$

$:\implies\rm{12(12\times12) - 15 \times12 + 3}$

$:\implies\rm{12\times144- 180+3}$

$:\implies\rm{1728-180+3}$

$:\implies\rm{1728+3-180}$

$:\implies\rm{1731-180}$

$:\implies\rm{1551}$

Thus ,

☆By putting the value of x as 3 the value of x we got is :

→$\orange{66}$

☆And,By putting the value of x as 12 the value of x we got is :

→$\red{1551}$
