Question

Factorize 18m²-39m+18

Answer 1

Answer:

18m² - 39m + 18 = 3(6m² - 13m + 6)

= 3(2m - 3)(3m - 2)

Answer 2

Answer:

18m²-26+18

so we have 3 in common

so,3[6m²-13+6]

by middle term splitting,

we can write 13 as -9-4 okay

3[6m²-9m-4m+6]

so we make pairs okk

3[(6m²-9m)-(4m-6)]

okay

3[3m(2m-3)-2(2m-3)]

now we have two pairs in common 2m-3

and (3m-2) is without pair

so we will write it as

3[(2m-3)(3m-2)]

so this is answer of any doubt then comment me
