Question

x^2-ax+a^2=0 find the discriminant of the equation

Answer 1

\[x ^{2}-ax+a ^{2}=0 \]this is the equation correct?

Answer 2

correct

Answer 3

What does the question ask you to do?

Answer 4

to find the discriminant

Answer 5

\(\bf ax^2+bx+c=0\qquad discriminant \implies b^2-4ac\\ \quad \\
x^2-ax+a^2=0\qquad \implies \textit{what do you think?}\)

Answer 6

notice your coefficients

Answer 7

I'm following jdoe

Answer 8

how do I deal with a^2

Answer 9

well, is just a variable, thus your discriminant will be in terms of "a"

Answer 10

a=1, b=a, c=a^2?

Answer 11

\(\begin{array}{llll}
&a&b&c\\
&1x^2&-ax&+a^2=0
\end{array}\qquad \bf \implies b^2-4ac\implies (-a)^2-4(1)(a^2)\)

Answer 12

-3a^2

Answer 13

yeap

Answer 14
