Find the value of m such that x^4– mx^2 + 6 is divisible by x^2 – 1. Answer: m =
Find the value of k such that x3 + kx2 + (4 - k)x - 35 is divisible by x - 7.
Answer: k = ........
Dịch: Tìm giá trị của k nếu :\(x^3+kx^2+\left(4-k\right)x-35⋮\left(x-7\right)\)
=>x-7=0=>x=7 => Là nghiệm của phương trình .
Thế x=7 vào biểu thức , ta có :
\(7^3+k.7^2+\left(4-k\right).7-35\)
=\(343+49k+28-7k-35=>42k=-336=>k=-8\)
Vậy k=-8
find the value of n such that the polynomial 2x^5 - 3x^3 + x^2 +n is divisible by the polynomial x+2
tìm giá trị của n sao cho đa thức 2x ^ 5 - 3x ^ 3 + x ^ 2 + n chia hết cho đa thức x + 2
Find the value of b such that the number 73b4 is divisible by 9?
Answer: b = .............
The value of b is 4 because ( 7 + 3 + 4 + 4) is divisible by 9
Find the value of b such that the number 73b4 is divisible by 9?
Answer: b = .............
Số nào có tổng chia hết cho 9 thì số đó chia hết cho 9.
Vậy b =4.
Ai thấy đúng thì k cho mình nha !!
give that \(x^4+ax+b\) is divisible by \(x^2-4\) . find the value of a +b
x^4+ax+b chia hết cho x^2-4
=>x^4+ax+b chia hết cho x-2 và x+2
x^4+ax+b=(x-2)(x^3+2x^2+4x+a+8)+(b+2(a+8))
x^4+ax+b chia hết cho x-2=>b+2(a+8)=0
x^4+ax+b=(x+2)(x^3-2x^2+4x+a-8)+(b+2(8-a))
x^4+ax+b chia hết cho x+2=>b+2(8-a)=0
=>b+2(a+8)=b+2(8-a)
<=>2a+16=16-2a
<=>4a=0
<=>a=0=>b=-16
Tại a=0,b=-16 ,giá trị của a+b=0+(-16)=-16
Find the value of b such that the number 73b4 is divisible by 9?
The value of b is: 4. Because 7344 divisible by 9
