Quadratic Discriminant
What is the discriminant of the quadratic polynomial \(4x^2+11x+1\)?
If the discriminant of the quadratic \( 2x^2 + ax + 72 \) is 0, what is \( a \) if \( a > 0 \)?
If \(a\) is a nonzero real number, what is the discriminant of the quadratic polynomial \[ax^2-8x-\frac{1}{a}?\]
If \(a\) and \(b\) are real numbers such that the discriminant of the quadratic polynomial \[\frac{11}{2}x^2+2(a+11b)x+8ab\] equals \(0\), what is \(\frac{a}{b}\)?
What is the discriminant of the quadratic \( x^2 - 10x + 2 \) ?
