X 3-3x 2-3x is a cubic trinomial.
X 3 refers to the cube of X, and X 2 refers to the square of X.
In polynomials, each monomial is called a polynomial term. Items without letters are called constant items. When determining the terms of a polynomial, we should pay special attention to the symbols of the terms. For example, the polynomial x2-3x+2*** has three terms, namely x2, -3x and 2. The second term is "-3x", not "3x", and 2 is a constant term.
"Inquiry method" can be used in trinomial mathematics teaching. The essence of "inquiry method" is student-oriented, which makes students change from passive acceptance of knowledge to knowledge explorers. Through hands-on operation, positive thinking, heated discussion and exploration of knowledge, students can better understand the connotation of knowledge and cultivate their own abilities of observation, thinking, hands-on, induction, language expression and creativity.
"Inquiry teaching method?" It refers to a comprehensive teaching method in which students discover knowledge rules, summarize conclusions, learn new knowledge, develop their thinking and cultivate their abilities through specific operations and personal attempts under the guidance of teachers. By letting students know the contents of polynomials, they can be guided to actively think about the knowledge of trinomial. Expand students' thinking and improve their independent thinking ability.
