Question

find the value of discriminant for the quadratic equationx2+7x+6​

Answer 1

$Compare \: given \: Quadratic\: equation$

$x^{2} + 7x + 6 \: with \: ax^{2}+bx+c ,we \:get$

$a = 1, b = 7 \: and \: c = 6$

$Discreminant = b^{2} - 4ac$

$= 7^{2} - 4 \times 1 \times 6$

$= 49 - 24$

$= 25$

Therefore.,

$\red{Discreminant }\green { = 25}$
