Answer»

Answer:x=3

x=23−−7

=23−i7

=1.5000−1.3229i

x=23+−7

=23+i7

=1.5000+1.3229i

Step-by-step explanation:(1): "x2" was REPLACED by "x^2". 1 more similar replacement(s). (((x3) - (2•3x2)) + 13x) - 12 = 0

2.1 x3-6x2+13x-12 is not a perfect cube 2.2 FACTORING: x3-6x2+13x-12

Thoughtfully SPLIT the EXPRESSION at hand into groups, each group having two terms :

Group 1: 13x-12

Group 2: -6x2+x3

Pull out from each group separately :

Group 1: (13x-12) • (1)

Group 2: (x-6) • (x2)
