Question

-8n^2 - 10n +1272=0 factorize​

Answer 1

Thnkx for asking ❤️☺️

factorize

-8n²-10n+1272=0

-2*(4n²+5n-636)=0

(4n²+5n-636)=0/-(2)

4n²+5n-636=0

1st multiply first term with last term

i.e 4n²*636

It would be 2544

Then Next step is to split middle term in that way that by adding or by subtracting answer would be 5n or by multiple same number answer would be 2544.

❤️So to split 5n in two parts which multiple is 2544 are ....

48 and 53 ☺️

To verify...

48 x 53 = 2544

and

by subtracting same number

i.e 53n - 48n =5n

4n²+5n-636=0

4n²+53n-48n-636=0

n(4n+53)-12(4n-53)=0

(4n+53) (n-12)=0

4n+53=0 n-12=0

4n=0-53 n=0+12

4n=(-53) n=12

n=(-53)/4 n=12

Hope it is helpful to you
