Hello, please consider the following.
When and
are two roots, we can factorise as
So for the first equation, we can say that the sum of the zeros is
and the product is
So we can factorise as below.
And the solutions are
For the second equation, we will complete the square and put the constant on the right side and take the root.
Let's do it!
We take the root, and we find the two solutions
Thank you.
