1.When kx^3+x^2-x-3 is divided by x+2,the remainder is 5.... 3.When x^3+kx^2+kx+5 is divided by 4x+3,the remainder is 11....
1+1=2 1 plus 1 equals 2 2x2=4 2 times 2 is 4 3-3=0 3 minus 3 is 0 56÷7=8 56 divided by 7 equals 8
設此直線為 y = mx 並設此直線與題目的拋物線交點為 ( a , ma ) 繪出拋物線的簡圖可知: (1) 拋物線與 x 軸交於 x = 0 與 x = 2 (2) 拋物線與 x 軸所圍成的區域在第一象限, 因此: m > 0 , 0 < a < 2 交點 ( a , ma ) 通過 y = mx 與 y = 4x - 2x² 因此 : ma = 4a...
