Question

Write the discriminant of the following equation
1) x² + px +2q = 0

Answer 1

       $\underline{\bold{Solution:}}$

       $\text{The discriminant}(\delta) \text{ of a quadratic equation, of the form }ax^{2} + bx + c\\\text{is }b^{2} - 4ac$

$\implies \text{The discriminant of }x^{2} + px + 2q = 0 \text{ is:}$

       $\delta = (p)^{2} - 4(1)(2q)$

$\implies \boxed{\delta = p^{2} - 8q}$

Answer 2

Step-by-step explanation:

d=b2-4ac

d=(px)2-4x2*2q
