    b=-19

    Step-by-step explanation:

    We know that one of the solutions is x=-4/5

    That is a solution to x. So if we plug in (-4/5) into the x in the equation, then it should equal 0.

    5 (-4/5) ^2+b (4/5) + 12=0

    Now, just solve for b.

    5 (16/25) + b (4/5) + 12=0

    (16/5) + (4/5) b+12=0

    (76/5) + (4/5) b=0

    (4/5) b = - (76/5)

    b=-19
