    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}

    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} }
