Find x (x+13)(x-7)=0
alex41 [277]

So for this, we will be applying the <u>zero product property</u>, which is <u>"if a x b = 0, then either a = 0 or b = 0 or both a and b = 0"</u>. In this case, a = x + 13 and b = x - 7. Solve them separately:

x+13=0\\ x=-13\\ \\ x-7=0\\ x=7

<u>Your answer is x = -13 and 7.</u>

Find the zeros of the function.
vlabodo [156]
The answer is 
f(x) = 9x3 + 18 x2 - 135x can be written as f(x) = x( 9x2+ 18 x - 135)
the first zero must be = 0
let's find the another zeros by solving 9x2+ 18 x - 135=0
f(-5)=135-135=0, so the answer is 
<span>
0, -5, and 3 

because </span><span>f(x) = 9x3 + 18 x2 - 135x =x (x+5)(x-3)</span>

Which procedure justifies whether Negative 3 x (5 minus 4) + 3 (x minus 6) is equivalent to Negative 12 x minus 6? The expressio
BlackZzzverrR [31]

Answer:

  The expressions are not equivalent because Negative 3 (2) (5 minus 4) + 3 (2 minus 6) = negative 18 and Negative 12 (2) minus 6 = negative 30

Step-by-step explanation:

Apparently, we're trying to see if ...

  -3(x)(5 -4) + 3(x -6) = -12(x) -6

by evaluating the expressions for x=2:

  -3(2)(5-4) +3(2 -6) ?= -12(2) -6

  -6 -12 ?= -24 -6

  -18 ≠ -30 . . . . . . . . . shows expressions are not equivalent

__

This demonstration matches the one in the first choice:

The expressions are not equivalent because Negative 3 (2) (5 minus 4) + 3 (2 minus 6) = negative 18 and Negative 12 (2) minus 6 = negative 30
