Question

# x^2+8x+15

Transformations of functions
$$\displaystyle{x}^{{2}}+{8}{x}+{15}$$
We are given: $$\displaystyle{x}^{{2}}+{8}{x}+{15}$$
To factor trinomials in the form $$\displaystyle{x}^{{2}}+{b}{x}+{c}$$, think of two factors of c (which are m and n) that add to b so that it factors to (x+m)(x+n).
