Question

Solve this equation by completing the square p^2 + 16p - 17 = 0

Answer 1

Answer: p=1

Step-by-step explanation:

$p^{2}+16p-17=0\\p^{2}+16p=17\\1^{2}+16(1)=17\\1+16=17\\p=1$

(p-1)(p+16)

Also, here's the cross method in completing the square that I tried in the file attachment. I haven't done this in a while, so this may not be neat.
