化归法是通过数学知识和方法将不熟悉的问题转化为熟悉的问题的数学方法.在下面的内容中,将重点介绍化归法在高中代数中的应用.例1(1999年高考试题理科)若(2x+√3)~4=a_0+a_1x+a_2x~2+a_3x~3+a_4x~4,那么(a_0+a_2+a_4)~2-(a_1+a_3)~2的值是().(A)1(B)-1(C)0(D)2思考方法上述问题如果你能找到“(a_0+a_2+a_4)~2-(a_1+a_3)~2=(a_0+a_1+a_2+a_3+a_4)(a_0-a_1+a_2-a_3+a_4)”之间的联系,就说明你学会化归法的使用方法.
In the following content, we will introduce the application of the law of return to normalization in high school algebra.Example 1 (1999 college entrance examination subjects science If (2x + √3) ~ 4 = a_0 + a_1x + a_2x ~ 2 + a_3x ~ 3 + a_4x ~ 4, the value of (a_0 + a_2 + a_4) ~ 2- (a_1 + a_3) ~ 2 is (). (A) 1 (B) -1 (C) 0 (D) 2 Thinking Method If you can find the above problem if you can find “a_0 + a_2 + a_4 ~ 2 - a_1 + a_3 2 = a_0 + a_1 + a_2 + a_3 + a_4) (a_0-a_1 + a_2-a_3 + a_4) ”, it shows you how to learn how to use the conversion law.
