Which of the following expressions are factors of p(x)=60x4+24x3−45x2−18x?
Whitepunk [10]

The factors are 3x, 4x^2-3 and 5x+2

So, Option B, C and F are correct.

Step-by-step explanation:

We need to find factors of the expression p(x)=60x^4+24x^3-45x^2-18x

Solving the expression: p(x)=60x^4+24x^3-45x^2-18x

Taking 3x common:

p(x)=3x(20x^3+8x^2-15x-6)

Now, factor by grouping, the terms inside the bracket.

p(x)=3x((20x^3+8x^2)+(-15x-6))

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

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

So, the factors are 3x, 4x^2-3 and 5x+2

So, Option B, C and F are correct.

Total profit P is defined as total revenue R -= total cost​ C, and is given by the function Upper P left parenthesis x right par
Goshia [24]

Answer:

Step-by-step explanation:

P(x) = R(x) - C(x)

Where,

P(x) = Total profit

R(x) = Total revenue

C(x) = Total cost

R(x)equals150.97 x minus 0.3 x squared

R(x) = 150.97x - 0.3x^2

Upper C left parenthesis x right parenthesis equals 4529.10 plus 0.5 x squared.

C(x) = 4529.10 + 0.5x^2

P(x) = R(x) - C(x)

= (150.97x - 0.3x^2) - ( 4529.10 + 0.5x^2)

= 150.97x - 0.3x^2 - 4529.10 - 0.5x^2

= 150.97x - 0.8x^2 - 4529.10

P(x) = -0.8x^2 + 150.97x - 4529.10
