Question

how to solve this m^2 - 4m + 4

Answer 1

Step-by-step explanation:

by splitting the middle term

m^2-4m+4=0

m^2-2m-2m+4=0

m(m-2)-2(m-2)=0

(m-2)(m-2)=0

m=2. Answer...

Answer 2

Step-by-step explanation:

$m ^{2} - 4m + 4 \\ = m^{2} - 2m - 2m + 4 \\ = m(m - 2) - 2(m - 2) \\ = (m - 2)(m - 2) \\ = (m - 2) {}^{2} \\ m - 2 = 0 \\ m = 2$
