So we gots apolynomial equation that is 3rd degree and crosses x axis at x=-1, x=0 and x=2
the factors of a poly equation that passes through r1,r2,r3 is
(x-r1)(x-r2)(x-r3)
so
r1=-1
r2=0
r3=2
f(x)=(x-(-1))(x-0)(x-2)
f(x)=(x+1)(x)(x-2)
f(x)=x³-x²-2x
leading coefient is posiitve because 3rd degree equations that are postive go bottom left to top right
yah
actually that looks like the exact graph
both
f(x)=(x+1)(x)(x-2)
and
f(x)=x³-x²-2x
are correct
The given number is not a solution of the equation i.e. the number is an inequality
<h3>How to determine the solution?</h3>
The equation is given as:
3x- 4 = 10
The number is given as:
5
This means that
x = 5
Substitute x = 5 in 3x- 4 = 10
3 * 5- 4 = 10
Evaluate the product
15- 4 = 10
Evaluate the difference
11 = 10
The above equation is not true i.e. the equation is actually an inequality
Hence, the given number is not a solution of the equation i.e. the number is an inequality

Answer:
y - 2 = (1/8)(x + 8)
Step-by-step explanation:
The slope of the given line is -8. That means the slope of any line perpendicular to the given line will be the negative reciprocal of -8, which would be (1/8).
Then the desired equation is
y - 2 = (1/8)(x + 8)
the answer should be C. 5.27
Answer:
Part A: x = 4.
Part B: The answer normally would be x = 12, but since your question asked why it has no real solution, it is because the solution (x=12) does not make the equaion true. Why? Because the value given from the equation that should make the equation true does not relate the equation in itself; hence making it have no solution.
