Factor f(x) = 15x^3 - 15x^2 - 90x completely and determine the exact value(s) of the zero(s) and enter them as a comma separated

Illusion [34]

Answer:

$x=-2,0,3$

Step-by-step explanation:

We have been given a function $f(x)=15x^3-15x^2-90x$ . We are asked to find the zeros of our given function.

To find the zeros of our given function, we will equate our given function by 0 as shown below:

$15x^3-15x^2-90x=0$

Now, we will factor our equation. We can see that all terms of our equation a common factor that is $15x$ .

Upon factoring out $15x$ , we will get:

$15x(x^2-x-6)=0$

Now, we will split the middle term of our equation into parts, whose sum is $-1$ and whose product is $-6$ . We know such two numbers are $-3\text{ and }2$ .

$15x(x^2-3x+2x-6)=0$

$15x((x^2-3x)+(2x-6))=0$

$15x(x(x-3)+2(x-3))=0$

$15x(x-3)(x+2)=0$

Now, we will use zero product property to find the zeros of our given function.

$15x=0\text{ (or) }(x-3)=0\text{ (or) }(x+2)=0$

$15x=0\text{ (or) }x-3=0\text{ (or) }x+2=0$

$\frac{15x}{15}=\frac{0}{15}\text{ (or) }x-3=0\text{ (or) }x+2=0$

$x=0\text{ (or) }x=3\text{ (or) }x=-2$

Therefore, the zeros of our given function are $x=-2,0,3$ .

Rewrite the equation without absolute value <br> Y=|x-2|+|x+2|-|x-5| if x<-2

Oxana [17]

Answer:

Step-by-step explanation:

Hey there!

In order to solve this equation, you need to first simplify and take the absolute value:

x+2+x+2-x+5

Now you need to simplify

x+9

So, the rewritten form of the equation is x+9

Tell whether the following equations are true or false. Then, explain your reasoning.

lorasvet [3.4K]

Answer and explanation:

Given : Equations

1) $x + 6g-6g = x$

2) $2f-4e + 4e = 2f$

To find : Tell whether the following equations are true or false. Then, explain your reasoning.

Solution :

Equation means when left hand side and right hand side of the equation is same.

1) $x + 6g-6g = x$

Take LHS,

$LHS=x + 6g-6g$

Same term with opposite sign cancel each other or sum is zero,

$LHS=x$

$LHS=RHS$

Therefore, Yes, it is true as it satisfy definition of equation.

2) $2f-4e + 4e = 2f$

Take LHS,

$LHS=2f-4e + 4e$

Same term with opposite sign cancel each other or sum is zero,

$LHS=2f$

$LHS=RHS$

Therefore, Yes, it is true as it satisfy definition of equation.
