Question

The discriminant of 6x2 -5x + 1 = 0 is ....
(A) 1
(B) 2
(C) 6
(D)-5/6
​

Answer 1

Answer:

$\huge{\underline{\underline{Given→}}}$

• $\sf\green{Equation→6x^2-5x+1=0}$

$\huge{\underline{\underline{To\:Find→}}}$

$\sf\purple{→Discriminant(D)\:of\:the\:given\:equation.}$

$\huge{\underline{\underline{Answer→}}}$

$As\:Discriminant(D)=b^2-4ac$

$Where\implies$

• $b=Coefficient\:of\:x.$
• $a=Coefficient\:of\:x^2.$
• $c=Constant\:term.$

$\sf{\underline{\underline{\color{blue}{So\:Discriminant\implies}}}}$

$\sf\blue{→D=b^2-4ac}$

$\sf\blue{→D=(-5)^2-4(6)(1)}$

$\sf\blue{→D=25-24}$

$\sf\blue{→D=1}$

$\sf{\boxed{\boxed{\pink{→D=1✔}}}}$

☞ So Discriminant(D) of the given equation is 1 which is the required answer.

→Hence option a) 1 is the correct answer.
