首先列表,利用未知數(shù)的取值,根據(jù)一元二次方程的一般形式ax2+bx+c=0(a,b,c為常數(shù),a≠0)分別計(jì)算ax2+bx+c的值,在表中找到使ax2+bx+c可能等于0的未知數(shù)的大致取值范圍,然后再進(jìn)一步在這個(gè)范圍內(nèi)取值,逐步縮小范圍,直到所要求的精確度為止.(2)在估計(jì)一元二次方程根的取值范圍時(shí),當(dāng)ax2+bx+c(a≠0)的值由正變負(fù)或由負(fù)變正時(shí),x的取值范圍很重要,因?yàn)橹挥性谶@個(gè)范圍內(nèi),才能存在使ax2+bx+c=0成立的x的值,即方程的根.三、板書(shū)設(shè)計(jì)一元二次方程的解的估算,采用“夾逼法”:(1)先根據(jù)實(shí)際問(wèn)題確定其解的大致范圍;(2)再通過(guò)列表,具體計(jì)算,進(jìn)行兩邊“夾逼”,逐步獲得其近似解.“估算”在求解實(shí)際生活中一些較為復(fù)雜的方程時(shí)應(yīng)用廣泛.在本節(jié)課中讓學(xué)生體會(huì)用“夾逼”的思想解決一元二次方程的解或近似解的方法.教學(xué)設(shè)計(jì)上,強(qiáng)調(diào)自主學(xué)習(xí),注重合作交流,在探究過(guò)程中獲得數(shù)學(xué)活動(dòng)的經(jīng)驗(yàn),提高探究、發(fā)現(xiàn)和創(chuàng)新的能力.
