factor theorem

Let us solve problem using factor theorem

Find a so that x⁴+2x³-ax²+x-2 has (x+2) as its factor.
Let p(x) = x⁴+2x³-ax²+x-2

When p(x) is divided by x+2 [x- (-2)],

R = p(-2)

= (-2)⁴+2(-2)³-a(-2)²-2-2

= 16-16-4a-4

= -4a - 4

As (x+2) is a factor, R=0

-4a - 4 = 0

a = -1

linear algebra toolkit

let us learn about linear algebra toolkit

The Linear Algebra Toolkit is comprised of modules designed to help a tutor & linear algebra student learn & practice a basic linear algebra procedure, such as calculating the determinant, Gauss-Jordan reduction, or checking for linear independence.

Solve for y: y + 8 = 15

Solution: y + 8 = 15
Subtract 8 from both sides of the equation
y + 8 – 8 = 15 – 8
y = 7
The answer y is 7.

simplifying calculator

Let us solve problem by using simplifying calculator
1.√x + 6 =10
6 is subtract on both sides
√x + 6 -6 = 10 - 6
√x = 4
X^2 = 2^2
x=2
2. Problem √x + 21 = 46
21 is subtract on both sides
√x + 21 – 21 = 46 – 21
√x = 25
X^2 = 5^2
x=5

poisson distribution examples

Let us learn about poisson distribution examples
Poisson distribution is a limiting method of binomial distribution. Poisson distribution occurs when there are events that do not occur as outcomes of a definite number of outcomes.
Poisson distribution is applied under the following conditions:
Number of trials “n” tends to infinity
Probability of success “p” tends to zero &
np = one is finite.

The Poisson distribution is an exact & correct model for count data

The Poisson distribution resembles the binomial distribution when the probability of an event is very small.
