x2 + 10x + 4

Based on the question, how do you know if you do this:

(x + 5)2 - 21

Or this:

(x + 5)2 = 21

x + 5 = +/- sqrt(21)

x = -5 +/- sqrt(21)

(x + 5)2 - 21: use this when the question says to write in vertex form.


(x + 5)2 = 21

x + 5 = +/- sqrt(21)

x = -5 +/- sqrt(21)

Use this when the question says Solve
