What is the remainder to x^3+4x^2+x-6 divided by (x-1)
serg [7]

x^3=x^2\cdot x, and x^2(x-1)=x^3-x^2. This gives a remainder of

(x^3+4x^2+x-6)-(x^3-x^2)=5x^2+x-6

5x^2=5x\cdot x, and 5x(x-1)=5x^2-5x. This gives a new remainder of

(5x^2+x-6)-(5x^2-5x)=6x-6

6x=6\cdot x, and 6(x-1)=6x-6. This gives a new remainder of

(6x-6)-(6x-6)=0

and so there is no remainder.

###

Quicker method: Use the polynomial remainder theorem, which says the remainder upon dividing a polynomial p(x) by x-c is p(c). Here we have

p(x)=x^3+4x^2+x-6

c=1\implies p(c)=1+4+1-6=0

-3g = -7
Divide both sites with 3.
-g = -7/3
Multiply both sides with -1
g = 7/3

Naily [24]

Answer:

Blake's total number of cards now:  1.25b

Step-by-step explanation:

Total number of cards now would be equal to 25% increase from b.

<em>This means we INCREASE b by 25% OF b.</em>

<em />

What is 25% of b???

\frac{25}{100}*b\\=0.25b

Now we need to ADD this to original amount, b.

So,   b+0.25b=1.25b
