The production cost, represented by y, of smart phone devices are equal to the product of computing components (a) and the squar

Marta_Voda [28]

The production cost is an illustration of a quadratic function

<h3>How to determine the equation</h3>

We have the following parameters:

Computing components (a)
Number of devices (x),
Labor (b)
Savings on reusable material (c)

Using the instructions in the question, the equation of the production cost would be:

$y =ax^2 + bx -c$

Hence, the production cost is $y =ax^2 + bx -c$

<h3>Change the subject of the equation</h3>

In (a), we have:

$y =ax^2 + bx -c$

Subtract bx - c from both sides

$y - bx + c = ax^2$

Divide through by x^2

$a = \frac{y - bx + c}{x^2}$

Hence, the equation that represents the computing component is $a = \frac{y - bx + c}{x^2}$

Find all the zeros of the equation

lapo4ka [179]

Divide both sides by -3, and replace $x^2$ with $y$ . Then

$-3x^4+27x^2+1200=0\iff y^2-9y-400=0$

Factorize the quadratic in $y$ to get

$y^2-9y-400=(y+16)(y-25)=0\implies y=-16,y=25$

which in turn means

$x^2=-16,x^2=25$

But $x^2\ge0$ for all real $x$ , so we can ignore the first solution. This leaves us with

$x^2=25\implies x=\pm\sqrt{25}=\pm5$

If we allow for any complex solution, then we can continue with the solution we ignored:

$x^2=-16\implies x=\pm\sqrt{-16}=\pm i\sqrt{16}=\pm4i$

Answer:

Step-by-step explanation:

Factor: -7x^2 -5x+18

Factor -1 out of 7x^2 -5x +18:

−(7x^2+5x−18)

Factor.

1. 18 is negative, so a negative number multiplied by a postive number.

2. You can't factor 7, so 7x times x.

(7x−9)(x+2)
