What two rational expressions sum to 3x+4/x^2-6x+5?

Lubov Fominskaja [6]

Answer:

$\frac{3x+4}{x^2-6x+5}=\frac{-7}{4(x-1)} +\frac{19}{4(x-5)}$

Step-by-step explanation:

The given rational expression is:

$\frac{3x+4}{x^{2}-6x+5} = \frac{3x+4}{(x-1)(x-5)}$

We can use concept of Partial Fractions to solve this problem. Let,

$\frac{3x+4}{(x-1)(x-5)}=\frac{A}{x-1} +\frac{B}{x-5}$

Multiplying both sides by (x - 1)(x - 5), we get:

$3x+4=A(x-5)+B(x-1)$

Substituting x = 5, we get:

$3(5)+4=A(5-5)+B(5-1)\\\\ 15+4=0+4B\\\\ 19=4B\\\\ B=\frac{19}{4}$

Substituting x = 1, we get:

$3(1)+4=A(1-5)+B(1-1)\\\\ 7=-4A\\\\ A=-\frac{7}{4}$

Substituting the value of A and B, back in the original equation, we get:

$\frac{3x+4}{x^2-6x+5}=\frac{-7}{4(x-1)} +\frac{19}{4(x-5)}$

1.In the diagram of circle M shown, various points are located on the circle as shown.   a) List three segments that are radii o

dalvyx [7]

Answer:

(a)|MA|, |MB| and |MC|

(b) |BD|

(c) |BC|

Step-by-step explanation:

An adapted diagram of this question is attached. You can vary the labelled letters as required.

<u>Definition</u>

A <u>radius </u>is a line drawn from the center of a circle to its circumference.
A <u>segment </u>is a line that connects two points.
A <u>diameter</u> is a chord which passes through the center of the circle.
A <u>chord</u> is any line joining two points on the circles' circumference.

By these definitions:

(a)Segments that are radii of this circle.

We have: |MA|, |MB| and |MC|

(b)Segment that is a diameter of this circle.

|BD|

(c)A chord of this circle that is not a diameter.

|BC|

Given a≠±b and a^2−b^2 / a+b =12, find a−b.<br> pls hlep

Readme [11.4K]

Answer:

a - b = 12

Step-by-step explanation:

Given

$\frac{a^2-b^2}{a+b}$ = 12 ← factor the numerator

a² - b² ← is a difference of squares and factors as

a² - b² = (a - b)(a + b)

Thus

$\frac{(a-b)(a+b)}{a+b}$ = 12

Cancel the common factor (a + b) on numerator/ denominator, thus

a - b = 12
