Question

m^2+20m +100
factorise by splitting middle term
​

Answer 1

Answer:

${m}^{2} + 20m + 100 = {m}^{2} + 10m + 10m + 100 \\ = m(m + 10) + 10(m + 10) \\ = (m + 10)(m + 10)$

Answer 2

Answer:

m^2+20m+100

{Multiply the first and the last term}

1*100=100

find factors of 100 and split such a way that the middle term when added equals to 20m and when multiplied it is 100

m^2+10m+10m+100

m(m+10)+ 10(m+10)

(m+10)(m+10)
