Answer 1

The correct answer is option A.

I just did the quiz to this and got it right.

Hope this helps and have a gr8 day <3

Answer 2

For this case we have the following polynomial:

`image`

Rewriting the polynomial we have:

`image`

From here, we can solve the polynomial using the quadratic equation

We have then:

`x=(-b+/-√(b^2-4ac))/(2a)`

`x=(-11+/-√(11^2-4(1)(-4)))/(2(1))`

`x=(-11+/-√(11^2+16))/(2)`

`image`

`image`

Therefore, the solutions are:

`image`
