How to factorize a quadratic polynomial with single variable?Quadratic polynomial with single variables are expressible in the form
[tex]ax^2 + bx + c[/tex] where x is the variable and a,b,c are constants.
Its factored form is
[tex]\dfrac{1}{4a^2} \times (2ax +b-\sqrt{b^2 - 4ac})(2ax +b+ \sqrt{b^2 - 4ac})[/tex]
Using the above method and finding the simplified form of the given expressionThe given expression is
[tex]\dfrac{x}{x^2 + 3x + 2} + \dfrac{3}{x + 1}[/tex]
Factorizing [tex]x^2 + 3x +2[/tex] using the aforesaid method, as we have got
a = 1, b = 3, c = 2,
thus, we have
[tex]ax^2 + bx + c = \dfrac{1}{4a^2} \times (2ax + b-\sqrt{b^2 - 4ac})(2ax +b + \sqrt{b^2 - 4ac})\\\\\begin{aligned}x^2 + 3x + 2 &= \dfrac{1}{4}(2x + 3 - \sqrt{9-8})(2x + 3 + \sqrt{9-8})\\\\&= \dfrac{1}{2}(2x+2) \times \dfrac{1}{2}(2x+4)\\&= (x+2)(x+1)\end{aligned}[/tex]
Thus, the given sum is
[tex]\begin{aligned}\dfrac{x}{x^2 + 3x + 2} + \dfrac{3}{x + 1} &= \dfrac{x}{(x+2)(x+1)} + \dfrac{3}{x + 1} \times \dfrac{(x+2)}{(x+2)}\\\\&= \dfrac{x + 3(x+2)}{(x+1)(x+2)} \\&= \dfrac{4x + 6}{(x+1)(x+2)}\\\end{aligned}[/tex]
Thus, the numerator of the simplified sum is [tex]4x + 6[/tex]

There are 40 students in class A. There are 5% more students in class B. How many students are in class B?
Answer:
Solution,
⇒Total students in class A=40
⇒Class B=5%
Now,
5% of 40 students
→5/100 × 40=2 students
Again,
→Number of students in class B =40 students + 2 students
=42 students
Hence, there were 42 students in class B.
Step-by-step explanation:
There are 42 students in class B which is more than 5% of the number of students in class A.
What is a percentage?A percentage is a ratio or number that may be expressed as a fraction of 100. Moreover, it is denoted by the sign "%."
Given:
In Class A,
there are 40 students in total.
For class B,
we have a condition that there are 5% more students in class B.
Let n be the students in class B.
So, applying the percentage formula,
we get,
n = 40 + 40 x 5 /100
n = 40 + 200/100
n = 40 + 2
n = 42.
Therefore, the number of students in class B = 42.

Darlene and Lenny picked apples. Darlene filled 14 baskets and Lenny filled 8. if each basket holds 24 apples, how many more apples did Darlene pick than Lenny?
A.112
B.144
C.192
D.336
Answer: B. 144
Step-by-step explanation: It's 144 because if you multiply 14 x 24 you get 336 and then you multiply 8 x 24 and you get 192. Now you subtract 336 - 192 and you get 144.

The unit rate for number 9 which states: You create 15 centerpieces for a party in 5 hours is 5. Is this true or false.
Describe the graph that is produced by the equation (x-7)^2+(y+5)^2>25
Step-by-step explanation:
The equation will form a circle because it in the form of
[tex](x - h) {}^{2} + (y - k) {}^{2} = {r}^{2} [/tex]
First, let set the equation equal.
[tex](x - 7) {}^{2} + (y + 5) {}^{2} = 25[/tex]
Here the center will be (7,-5), and the radius of 5. The boundary line will be dashed
Since this is in the inequalities, we must find the solution set.
Plug in 0,0 for x and y and see if it's true.
[tex](0 - 7) {}^{2} + (0 + 5) {}^{2} > 25[/tex]
[tex]49 + 25 > 25[/tex]
[tex]74 > 25[/tex]
This is a true so we shade the region that includes 0,0
Since 0,0 has a greater distance from the center of the circle, 0,0 is outside of the circle, so our solution set will
be outside of circle.
Here a picture of graph,
