5^2 = 25

13^2 = 169

169 - 25 = 144

The square root of 144 = 12.

12 + 2 = 14.

a^2 + b^2 = c^2

5^2 + b^2 = 13^2

25 + b^2 = 169
-25 -25

b^2 = 144
sqrt sqrt

b = 12
+2

14

x^2 - 6x + 9 = 4 now subtract four from both sides

x^2 -6x+5 = 0 now factor ( or use quadratic formula)

(x-5)(x-1) = 0 so x = 5 or 1
