Multiply (x-1)(x³+4x²+4x-1) and combine like terms. Explain how you reached your answer.
Hitman42 [59]

Answer:

x⁴+3x³ -5x +1

Step-by-step explanation:

To multiply this we are going to <u>multiply each term of the binomial by each term of the polynomial.</u>

(x-1)(x^{3}+4x^{2}  +4x-1)\\=x^4+4x^3+4x^2-x -x^3-4x^2-4x+1

Now we are going to <u>combine like terms (this means we are going to sum up terms with the same exponent)</u>

x^4+4x^3+4x^2-x -x^3-4x^2-4x+1 = x^4 +(4x^3-x^3)+(4x^2-4x^2)+(-x-4x)+1\\=x^4+3x^3-5x+1

Thus, the answer is x⁴+3x³ -5x +1

A rectangle is (x+10)ft by (x+4)ft. If a square of length xft on a side is cut from the rectangle, represent the remaining area
Andrei [34K]

Answer: A(x)=14x+40

Step-by-step explanation:

Given : The dimension of a rectangle is  (x+10)ft. by (x+4)ft.

Then, Area of rectangle will be :-

A_1(x)=(x+10)\times(x+4)=x^2+(10+4)x+40\\\\\Rightarrow\ A_1(x)=x^2+14x+40

If a square of length xft on a side is cut from the rectangle, then the area of the square :-

A_2(x)=x^2

Now, the remaining area in the form of a polynomial function A(x) will be :-

A(x)=A_1(x)-A_2(x)\\\\=x^2+14x+40-x^2=14x+40

Hence, the  remaining area in the form of a polynomial function A(x) will be :-

A(x)=14x+40
