If it the question from basic algebra till high school maths , there must be a printing error . The last term should be 4 instead of +4. If it is that it can be solve as z2 will be one of the factor of the polynomial on LHS. If it is the question for higher maths, then differentiate both sides wrt x twice. u will get two imaginary roots as 3\[\pm \sqrt{21\div6}\]
