Which second-degree polynomial function f(x) has a lead coefficient of 4 and roots 5 and 2? f(x) = 4x² +7x+10 f(x)=4x²+28x+40 O
makkiz [27]

The second-degree polynomial function f(x) that has a lead coefficient of 4 and roots 5 and 2 is f(x) = 4x² -28x + 40. The correct option is the last option f(x)=4x²-28x+40​

<h3>Quadratic equation</h3>

From the question, we are to determine which second-degree polynomial function f(x) has a lead coefficient of 4 and roots 5 and 2

To determine this, we will use the given roots to determine the equation

The roots are 5 and 2

Thus

x = 5 and x = 2

x - 5 = 0 and x - 2 = 0

Therefore,

(x -5)(x -2) = 0

Distributing

x(x -2) -5(x -2)  = 0

x² -2x -5x + 10 = 0

x² -7x + 10 = 0

Now, multiplying through by 4, we get

4x² -28x + 40 = 0

Thus, the function becomes f(x) = 4x² -28x + 40

Hence, the second-degree polynomial function f(x) that has a lead coefficient of 4 and roots 5 and 2 is f(x) = 4x² -28x + 40. The correct option is the last option f(x)=4x²-28x+40​

If b = 3/x + 3/y <br> what is the value of 1/b
sashaice [31]

Answer:

  • xy / (3x + 3y)

Step-by-step explanation:

<u>Find b first:</u>

  • b = 3/x + 3/y
  • b = (3x + 3y)/xy

<u>Find 1/b:</u>

  • 1/b = 1 : (3x + 3y)/xy
  • 1/b = xy / (3x + 3y)
