Find aa and bb that make the equation true. verify your results.
a. a / x + 1 +b / x − 1 = 2 / x2 − 1
b. a / x + 3 + b / x + 2 = 2x − 1 / x2 + 5x + 6

a. A = -1 and B = 1

b. A = 7 and B = -5

Step-by-step explanation:

a.

To the equation be true, the "x-parts" and "nonx-parts" mist be the same, so:

Ax + Bx = 0

(A + B)x = 0

A + B = 0

A = -B

B - A = 2

B - (-B) = 2

2B = 2

B = 1  and A = -1

b.

To the equation be true, the "x-parts" and "nonx-parts" mist be the same, so:

Ax + Bx = 2x

(A + B)x = 2x

A + B = 2

A = 2 - B

2A + 3B = -1

2*(2-B) + 3B = -1

4 - 2B + 3B = -1

B = -5  and A = 2 - (-5) = 7

5 x 14?

im new, sorry if this is wrong.

step-by-step explanation:

the answer is thin because within context, the stanza concludes the and frail tone the people have toward each other, and the fact that it would be thin, makes the most sense compared to "pliable" or "not hard or firm to the touch". hope this , good luck.
