    (x - 7) (x + 2)

    Step-by-step explanation:

    Create equation-

    (x - 7) (x + 2)

    Multiply-

    Take the term multiply it with each variable or number and add with the product of the second term multiplied with the variable and number, as so:

    x * x = x^2

    x * 2 = 2x

    -7 * x = - 7x

    -7 * 2 = - 14

    x^2 + 2x - 7x - 14

    Combine like terms

    x^2 - 5x - 14

    To confirm

    -14

    -7 and 2 go into - 14 and add to - 5
