For this case we must write a quadratic equation of the form:

[tex]x ^ 2 + bx + c = 0[/tex]

We have two roots:

[tex]x_ {1} = - 7\\x_ {2} = 1[/tex]

Thus, we can rewrite the equation in a factored form as:

[tex](x + 7) (x-1) = 0[/tex]

If we apply distributive property we have:

[tex]x ^ 2-x + 7x-7 = 0[/tex]

Different signs are subtracted and the major sign is placed.

[tex]x ^ 2 + 6x-7 = 0[/tex]

Answer:

The quadratic equation is:

[tex]x ^ 2 + 6x-7 = 0[/tex]
