Answer:
Solution set = {(-1,-2/5)]
Step-by-step explanation:
64p=-16+8p-40p²
64p-8p=-16-40p²
56p+16+40p²=0
40p²+56p+16=0
8(5p² +7p+2)=0
5p²+5p+2p+2=0
5p(p+1) +2(p+1)=0
(p+1)(5p+2)=0
p+1=0; 5p+2=0
p=-1; p=-2/5
Answer:
x>10 or x< -2
Step-by-step explanation:
There are two solutions, one positive and one negative, remembering to flip the inequality for the negative
x-4 >6 or x-4 < -6
Add 4 to each side
x-4+4 > 6+4 or x-4+4 < -6+4
x>10 or x< -2
