Answer:
Step-by-step explanation:
let polynomial P(x)=ax³+bx²+cx+d
-3=-a+b-c+d
-2=d
-1=a+b+c+d
-1=a+b+c-2
a+b+c=1
-3=-a+b-c-2
a-b+c=1
a+b+c-(a-b+c)=1-1=0
2b=0
b=0
so a+c=1
6=8a+4b+2c+d
6=8a+4b+2c-2
8a+4b+2c=8
4a+2b+c=4
or 4a+0+c=4
4a+c=4
a+c=1
subtract
3a=3
a=1
1+c=1
c=0
reqd .P(x)=1x³-2=x³-2
Answer:
m4{=100 is the answer,,,,,,
Answer: i think you are supposed to subb in the x and h for something i just dont know what it is im not that smrt sorry i would thing it is 4 for x then the one would turn negative because in the equation it is subtraction so just do 4(4)^2+4-1 for the first one
the second one just do the same thing sub in the same numbers so it would be 4(4+1)-4(4)/1 i think it will get your answer brainliest plz
Step-by-step explanation:
Answer:
X=0,X=-3/7
Step-by-step explanation:
7x^2+3x=0
x(7x+3)=0
x=0
7x+3=0
7x=-3
x=-3/7.
