Question

expand and simplify 3 ( 4 c + 1 ) − 4 ( 4 c − 3 )

Answer 1

[ Answer ]

$\boxed{-4c \ + \ 15}$

[ Explanation ]

3(4c + 1) - 4(4c - 3)

[Expand] 3(4c + 1): 12c + 13

12c + 13 - 4(4c - 3)

[Expand] -4(4c - 3): -16c + 12

12c + 13 - 16c + 12

[Simplify] 13c + 13 - 16c + 12: -4c + 15

= -4c + 15

$\boxed{[ \ Eclipsed \ ]}$

Answer 2

To simplify any expression, add/subtract variables with same variable and constant with constant number.

After simplification,  We get, -4c + 15

Given that,    3 ( 4 c + 1 ) − 4 ( 4 c − 3 )

    Now open brackets.

                 $=12c+3-16c+12$

                  $=12c-16c+3+12\\\\=-4c+15$

Thus, after simplification We get, $(-4c+15)$
