Answer:

y=(x+5)(x+2)

Explanation:

Answer:

y=(x+5)(x+2)

Explanation:

Intercept form of quadratics is the best way to solve this equation, since you're given the roots needed.

The intercept form equation is y=a(x-p) (x-q) [where p and q are your roots/intercepts].

So, you input the intercepts and get y=(x-(-5))(x-(-2)), so your final answer should be y=(x+5)(x+2).
