If the roots of the equation xcubed + 3xsquared - 2x +1 = 0 are e, f, g
find the value of
a) esquared(f+g) + fsquared(g+e) + gsquared(e+f)
b) esquaredfsquared + fsquaredgsquared + gquaredesquared
this knowing that e+f+g=-b/a, ef+eg+fg=c/a and efg=-d/a (general cubic equation rules)
Solve the equation 4xcubed - 12xsquared +9x - 2 =0 given that two of its roots are equal
thankyou in advance for any help given ! appreciate it !
