CEMC Fermat, 2015 Difficulty 1.1 Junior Find the answer Canada
If x = − 3 x=-3 x = − 3 ( x − 3 ) 2 (x-3)^2 ( x − 3 ) 2
Pick one
A 12 12 12 B 36 36 36 C − 12 -12 − 12 D 0 0 0 E − 36 -36 − 36
Solution Evaluating, ( x − 3 ) 2 = ( − 3 − 3 ) 2 = ( − 6 ) 2 = 36 (x-3)^2=(-3-3)^2=(-6)^2=36 ( x − 3 ) 2 = ( − 3 − 3 ) 2 = ( − 6 ) 2 = 36
