Question

15 x²-2ax=a² by quadratic equations​

Answer 1

Answer:

x= a/3 & x= -a/5

Explanation:

$15 {x}^{2} - 2ax - {a}^{2} = 0 \\ (5x - a)(3x - a) = 0 \\ then \: x = \frac{a}{3} \: and \: x = \frac{ - a}{5}$

Answer 2

two roads diverged in a yellow wood,

and sorry I could not travel both

and be one traveller , long I stood

and looked down one as far as I could

to where it bent in the undergrowth;

then took the other, just as far,

and having perhaps the better claim,

because it was grassy and wanted wear;

through as for that the passing there

had worn them really about the same.

and both that morning equally lay

in leaves no step had trodden black.

oh, I kept the first for another day!

yet knowing how way leads on to way,

I doubted if I should ever come back.

I shall be telling this with a sing

somewhere ages and ages hence;

two roads diverged in a wood, and I ____

I took the one less travelled by,

and that has made all the difference,
