1 solve using the square root property 4m2 196 2 solve using

1. solve using the square root property: 4m2= 196

2. solve using the square root property: (x+5)^2=144

Solution

1. 4m^2 = 196

divide by 4 :

m^2 = 196/4 = 49

m^2 = 49

m^2 - 49 =0

(m+7)(m -7) =0

m = 7 ,-7

2. (x+5)^2 = 144

(x+5)^2 - 144 =0

(x+5)^2 - (12)^2 =0

(x +5 -12)(x+5 +12) =0

(x -7)( x+17) =0

x= 7 ; x= -17
