Answer :
3/2 ± √-3/2 is value of x does the curve have a horizontal tangent in quartic equation.
What does quartic equation mean?
A quartic equation, also known as an equation of the fourth degree, is an equation of the form that reduces a quartic polynomial to zero. in which a 0. A cubic function is a quartic function's derivative.
f(x) = x³−3x + 3
0 = x³−3x + 3
x = 3 ± √( -3)² - 4 * 1 * 3/2 * 1
x = 3 ± √9 - 12/2
x = 3 ± √-3/2
x = 3/2 ± √-3/2
