Question

x^4-144=0 solved using the quadratic formula

Answer 1

I will write it as :

\(x^2 + 0(x) - 144 = 0\)

Can you predict what are a, b and c here?

a = coefficient of x^2
b = coefficient of x
c = constant term

Answer 2

put x^2=t
\[t^2+0t-144=0,solve ~for ~t\]
then again replace t by x^2.
