If x²-1 is a factor of the polynomial, both x-1 and x+1 are factors of it.
According to the remainder theorem, if a binomial x-a is a factor of a polynomial p(x), then p(a)=0.
If x-1 and x+1 are factors of the polynomial p(x)=ax⁴+bx³+cx²+dx+e, then p(1)=0 and p(-1)=0.
Answer:
<u>400 miles</u>
Step-by-step explanation:
2 hours = 100 miles
Therefore, he will drive 4 times the distance given 4 times the time taken.
=> 100 x 4
=> <u>400 miles</u>
Answer:
1.68m2
Step-by-step explanation:
The area of a rectangle is given by (l = length, w = width):
A=l* w
So, in this case, we just have to plug in the numbers.
A=2.1m*0.8m=1.68m2
So, the area of the rectangle is 1.68 m².
