Question

Find the discriminant of the following equation.x2+5x-6=0

Answer 1

Answer:

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

• $\sf\green{Equation→x^2+5x-6=0}$

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

$\mathrm\purple{→Discriminant(D)\:of\:the\:equation}$

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

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

Where→

• $a=coefficient\:of\:x^2$
• $b=coefficient\:of\:x$
• $c=constant\:term$

$\sf\blue{→D=b^2-4ac}$

$\sf\blue{→D=(5)^2-4(1)(-6)}$

$\sf\blue{→D=25-4(-6)}$

$\sf\blue{→D=25+24}$

$\sf\blue{→D=49}$

$\sf{\boxed{\boxed{\pink{→D=49✔}}}}$

☞ Hence Discriminant(D) of the given equation is 49 which is the required answer.
