Answer 4

The roots of a quadratic equation is given \[x=\frac{-b-\sqrt{b^2-4ac}}{2a}\text{ and }\frac{-b+\sqrt{b^2-4ac}}{2a}\]

Now identify the values of a, b and c by comparing this equation to yours.

Substitute the values back in this and simplify the equations to solve for x.

Answer 5

a=1
b=-3
c=-1
just plug em in

Answer 6
