Đáp án+Giải thích các bước giải:
Ta có: `A=-3k+5/4`
Thay: `k=1 => A= -3.3 + 5/4 = -7/4`
`k=3 => A= -3.3 + 5/4= -31/4`
` k=5 => A= -3. 5 + 5/4= -55/4`
`k=7 => A= -3.7 + 5/4 = -79/4 `
`k=9 => A= -3.9 + 5/4 = -103/4`
`k=0 => A= -3.0 + 5/4 = 5/4`
`k=-4 => A= -2.(-4) + 5/4= 53/4`
`k=-8 => A= (-3)(-8) +5/4 = 101/4`
`k=-10 => A= (-3)(-10) + 5/4 = 125/4`
`k=-22 => A= (-3)(-22) + 5/4 = 269/4`
Ta có: `B=-3k+2/9+1/3`
Thay: `k=1 => B= 3.1 + 2/9+1/3 = 32/9`
`k=3 => B= 3.3 + 2/9+1/3 = 86/9`
`k=5 => b= 3.5 + 2/9+1/3 = 140/9`
`k=7 => B= 3.7 + 2/9+1/3 = 194/9`
`k=8 => B= 3.8 + 2/9+1/3 = 221/9`
`k=9 => B= 3.8 + 2/9+1/3 = 248/9`
`k=-10 => B= 3.(-10) + 2/9+1/3 = -265/9`
