Answer 3

Buth there's still an equation right?

Answer 4

Yeah, do you know factorization of trinomials?

Answer 5

You must express \(b\) as the sum of two numbers \(\alpha \) and \(\beta\) such that \(\alpha \times \beta = a \times c\), first of all.

Answer 6

In this case, \(\alpha \) and \(\beta \) are -5 and -5, respectively.

\( \color{Black}{\Rightarrow x^2 - 5x - 5x - 10 }\)

Did that help?
