Question

What is the value of n if 3x^2 - x-n =6, where x=1? ​

Answer 1

$\huge \fbox \red{Answer}$

x = 1

Then,

3x² - x - n = 6

3(1)² - 1 - n = 6

3 - 1 - 6 = n

2 - 6 = n

-4 = n

Hence, the value of n is -4.

Answer 2

${\huge{\green{\underline{\green{\boxed{\sf { \red{Answer :}}}}}}}}$

3x² - x - n = 6

3(1)² - 1 - n = 6

3 - 1 - 6 = n

2 - 6 = n

-4 = n

Hence, the value of n is -4
