Use the difference of squares factorization - that for any numbers a and b, (a-b)(a+b)=a^2-b^2.
We have:
(x^2+1)(x^2-1)=x^4-1
In addition:
(x-1)(x+1)=x^2-1, so we have:
(x^2+1)(x+1)(x-1)
As our complete factorization.

Answer:</h2>
<em>Question 10. </em><u><em>The truck travels faster</em></u><em>.</em>
<em>Question 11. </em><u><em>The slug travels faster</em></u><em>.</em>
<h2>
Step-by-step explanation:</h2>
<h2><u>Question 10.</u></h2>
<u />
<h3>1. Find the velocity of each vehicle.</h3>
<h3>2. Compare the velocities.</h3>
<em>Hence, the trucks travels faster than the car.</em>
<em></em>

<h2><u>Question 11.</u></h2>
<em>Apply the same method as in question 10.</em>
<h3>1. Find the velocity of each body.</h3>
<em />
<h3>2. Compare the velocities.</h3>
Hence, the slug travels faster.
Step-by-step explanation:
cos F = HF/FG
cos 52° = x/(4.3)
0.6 = x/4.3
=> x = 4.3 × 0.6
x = 2.58
so the length of HF = 2.58 = 2.6 ft
Answer:
<h3>x = -2 and 7</h3>
Step-by-step explanation:
- x^2 - 5x - 14 = 0
- x^2 - ( 7 - 2 )x - 14 = 0
- x^2 - 7x + 2x - 14 = 0
- x ( x - 7 ) + 2(x - 7) = 0
- (x + 2) (x - 7) = 0
- x = -2 and 7
