What is the value of a?

Mathematics
1 answer:
Sindrei [870]2 years ago
6 0

Answer:

a=2

Step-by-step explanation:

Firstly, in order to simplify the expression, we should aim to combine the two terms given. In order to do this, both must have the same denominator. We can give them the same denominator by multiplying the second term -\frac{2}{x+2} by \frac{x+2}{x+2}. This way the fraction value remains the same but now has the same denominator as the first term:

-\frac{2}{x+2} *\frac{x+2}{x+2} \\\\=\frac{(-2)(x+2)}{(x+2)(x+2)} \\\\=\frac{-2x-4}{(x+2)^{2}}

From here we can now combine the two terms:

\frac{2x+6}{(x+2)^{2}} +\frac{-2x-4}{(x+2)^{2}} \\\\= \frac{(2x+6)+(-2x-4)}{(x+2)^{2}} \\\\\\=\frac{2x+6-2x-4}{(x+2)^{2}}\\\\= \frac{2}{(x+2)^{2}}

Therefore, a = 2.

Hope this helped!

Find the term that must be added to the equation x2 6x=1 to make it into a perfect square.
andrezito [222]

The value added to the equation $x^2-6x=1 exists $x^2-6x+9=10.

<h3>What is a perfect square?</h3>

A perfect square exists as a number that can be described as the product of an integer by itself or as the second exponent of an integer.

The perfect square trinomial exists

(a ± b)^2 = a ^2 ± 2ab + b ^2

$x^2-6x=1

x^2-2*3x=1

then $2ab = 2 * 3*x = 2 * x *3

The value of a = x and b = 3

$b^2=3^2=9

$x^2-6x+9=1+9

$x^2-6x+9=10

The value added to the equation $x^2-6x=1 exists $x^2-6x+9=10.
