➡️ One contains 850 litres.

Another contains 680 litres.

➡️ Now, H. C. F of 850 and 680 is

= 170

➡️ $<b>Hence, The maximum capacity of a container which can measure the petrol is 170 litres. </b>$

➡️ We know that the constant term is the multiplication of the roots.

➡️ So, when it is 0, the multiplication of the roots is 0.

➡️ Hence, one of the roots is 0.

✨20

➡️ Coefficient of x is the sum of the roots.

➡️ When, coefficient of x is 0, Hence, the sum of the roots is 0.

➡️ Thus, the roots are equal in magnitude but with opposite signs.

✨21

➡️ Let, x and 3x.

➡️ 3x * x = 27.

Or, 3x^2 = 27

Or, x = 3.

And 3x = 9.

➡️ So, k = sum of roots

= 9 + 3 = 12.

✨22

➡️ Let, 2x and 3x.

➡️ 2x + 3x = 15

Or, x = 2.

➡️ 2x = 6 and 3x = 9.

➡️ Hence, the equation will be

= a^2 + a(6 + 9) + 6 * 9

= a^2 + 15x + 54.

That's it..
