    X = - 6 and 1

    To find the zeros you have to find two numbers that multiply to get - 6 and add to get 5

    The two numbers you can use are 6 and - 1.

    You then set these up with c

    (x+6) (x-1)

    Then set each of these up with 0

    x+6=0 x-1=0

    Then solve for them

    x=-6 x=1

    -6 and 1 are your solutions

    The zeros are x=1, x=-6

    Step-by-step explanation:

    f (x) = x^2+5x-6

    Factor: What two numbers multiply to - 6 and add to 5

    -1 * 6 = - 6

    -1 + 6 = 5

    f (x) = (x-1) (x+6)

    Using the zero product property

    0 = (x-1) (x+6)

    x-1 = 0 x+6=0

    x=1 x=-6

    The zeros are x=1, x=-6
