When factored completely, x3 − 13x2 − 30x is
1 answer:
Answer:
x (x - 15) ( x + 2)
Step-by-step explanation:
Start by factoring out x. Use a modified version of the distributive property.
x(x^2 - 13x - 30)
The second factor breaks down further into two facts in some form. The factors are 15 and 2
x(x 15)(x 2) One of them is positive and one negative. The larger number numerically (15) must be minus, because the 13 is minus.
x (x - 15) ( x + 2) is your complete answer.

<em>To find the zero,</em>
<em>x</em> + 1 - 4 = 0
<em>x</em> = 4 - 1
<em>x</em> = 3
3 is the <u>root</u> of <em>(x + 1) - 4</em>.

Answer:
Let w be the width. Then the length is 2w-4. So:
w(2w-4)=96
2w²-4w-96=0
w²-2w-48=0
(w-8)(w+6)=0
w=8 or -6
Throwing out the negative value for w, we get a width of 8 yds, and a length of 12 yds. ☺☺☺☺
Equality between the values, equations, or expressions written on both sides.
