What is a

Answer 1

Answer:

hope it helps you mate

Step-by-step explanation:

ab + ac = 1

ab = 1 - ac

a^2 = (1 - c)/b

a = $\sqrt{\frac{1-c}{b} }$

Answer 2

$ab + ac = 1 \\ a(b + c) = 1$

Splitting into 2 factors of 1, we get

CASE1 :

$a(b + c) = (1)(1)$

So by comparing, a = 1 is a Possible Solution

CASE2 :

$a(b + c) = ( - 1)( - 1)$

So by comparing, a = -1 is a Possible Solution.

Therefore, a = 1 and a = -1 are the values of a

BTW,

ab + ac =1

a(b+c) = 1

So, $a = \frac{1}{b+c}$
