Question

How do you solve `0 = x^2 + 5x + 6` graphically and algebraically?

Answer 1

Graphically, you plot the points and look for the intersection of the curve with the x-axis. Algebraically, you can use the quadratic formula or factoring.

Explanation:

Factoring:
`x^2 + 5x + 6 = 0` ; `(x + 2)(x + 3) = 0`
The roots are at `x = -2 and x = -3`
Graphically:
