First... expand the brackets

While expanding... you multiply all the terms with the term to be multiplied to

$2 a - 5 (a + 1) = 2 a - 5 a - 5$ $2a-5(a+1)=2a-5a-5$
Solve
$- 3 a - 5$ $-3a-5$

If you'll take 0
$- 3 a - 5 = 0$ $-3a-5=0$
$- 3 a = 5$ $-3a=5$
$a = - \frac{5}{3}$ $a=-5/3$

By Distributing; the answer is $- 3 a - 5$ $-3a-5$

Explanation:

Distribute the 5 into the parenthesis:

$2 a - 5 a - 5$ $2a-5a-5$

Simplify:

$- 3 a - 5$ $-3a-5$

$= - 3 a - 5$ $=-3a-5$

Explanation:

$2 a - 5 (a + 1)$ $2a-5(a+1)$

$= 2 a - 5 \times a - 5 \times 1$ $= 2a-5×a-5×1$

$= 2 a - 5 a - 5$ $= 2a-5a-5$

Thus,

$= - 3 a - 5$ $= -3a-5$

Answer 4 · 2018-03-04T15:56:58

$= - 3 a - 5$ $=-3a-5$

Explanation:

$2 a - 5 (a + 1)$ $2a-5(a+1)$

Distribute

$= 2 a + (- 5) (a) + (- 5) (1)$ $=2a+(-5)(a)+(-5)(1)$

$2 a - 5 a - 5$ $2a - 5a - 5$

$= - 3 a - 5$ $=-3a - 5$
