Question

Find the H.C.F of 3a +9 and 4a+ 12
​

Answer 1

Answer:

$(3a + 9) + (4a + 12 )\\ \\ 3a - 9 + 4a - 12 \\ 3a + 4a + 9 - 12 \\ - 1a - 21 \\ 22a$

take only 22 for hcf after HCF we get 11 is quotient and remainder 0

we can say 11×2=22 or 2×11=22

and the answer is 11a

or we take 22a for HCF and we divide it from 2 and then we

take 11 a has quotient and 0 as remainder

I hope it help you.......
