Question

Analyze the discriminant of the quadratic equation: h(x)=x^2-2x-35. How do I find the discriminant? Thank you so much !

Answer 1

discriminant=b^2-4ac
where you identity the a,b, and c from f(x)=ax^2+bx+c

Answer 3

if b^2-4ac is positive you have two real roots
if b^2-4ac is zero you have one real real root (with multiplicity 2)
if b^2-4ac is negative you have no real roots but 2 complex roots
