<span>((x+deltaX)^2+x+deltaX-(x^2+x))/deltaX = (x^2 + 2x delta x + (delta x)^2 + x + delta x - x^2 - x) / delta x = delta x (2x + delta x + 1) / delta x = 2x + delta x + 1
Therefore, </span>Lim as x tends to 0 of <span>((x + delta X)^2 + x + deltaX - (x^2 + x)) / deltaX</span> = 1 + delta x

<u>Complex Numbers</u>
The complex numbers are known by having an 'imaginary' part along with the real part. They can be expressed like a + bi, where
Or, equivalently:
Let's find the result of the following products. On each one of them, there is a sum of a binomial multiplied by the subtraction of a binomial with the very same terms. It leads to a well-known polynomial identity:
1.
Applying the above-mentioned identity:
Since

The cubic equation having roots 2, -1 and 4 is
Step-by-step explanation:
The roots of the cubic equation are 2,-1 and 4. We need to find the cubic equation.
If 2,-1 and 4 are roots then:
x=2, x=-1 and x=4
or we can write:
x-2=0, x+1=0 and x-4=0
Multiplying the roots to find the cubic equation:
So, the cubic equation having roots 2, -1 and 4 is

Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Point awarded for defeating a monster = 4
Points awarded for getting to the end of a stage = 9
Number of monsters defeated = m
Total number of points earned after finishing a stage = p
Total point earned = (Point awarded for defeating a monster * number of monsters) + points awarded for getting to final stage
p = (4 * m) + 9
p = 4m + 9
