<span>Simplifying 21.5x + -7.7 + -12.6x + 17 = 0 Reorder the terms: -7.7 + 17 + 21.5x + -12.6x = 0 Combine like terms: -7.7 + 17 = 9.3 9.3 + 21.5x + -12.6x = 0 Combine like terms: 21.5x + -12.6x = 8.9x 9.3 + 8.9x = 0 Solving 9.3 + 8.9x = 0 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-9.3' to each side of the equation. 9.3 + -9.3 + 8.9x = 0 + -9.3 Combine like terms: 9.3 + -9.3 = 0.0 0.0 + 8.9x = 0 + -9.3 8.9x = 0 + -9.3 Combine like terms: 0 + -9.3 = -9.3 8.9x = -9.3 Divide each side by '8.9'. x = -1.04494382 Simplifying x = -1.04494382</span>

I believe that the answer would be 26. First, put 26 for x and subtract 8.9 from 26 s 26 - 8.9 = 17.1. Next, you will subtract -4.5 from 17.1 which equals 12.6. So 26 is your answer.

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 $-3\text{ and }2$ .
